Optimal perioperative pain control regimens remain challenging and opioid analgesics are commonly used. Preoperative nonsteroidal anti-inflammatory drug (NSAID administration has been shown to reduce postoperative narcotic requirements. This study sought to evaluate the efficacy of perioperative intravenous (IV ibuprofen on postoperative pain level and narcotic use in patients undergoing open or laparoscopic inguinal and/or umbilical hernia repair.Methods: A single center, randomized, double-blind placebo-controlled trial involving patients ≥18 years undergoing inguinal and/or umbilical hernia repair was performed. Patients were randomized to receive 800 mg of IV ibuprofen or placebo preoperatively. Outcomes assessed included postoperative pain medication required and visual analog scale (VAS pain scores.Results: Forty-eight adult male patients underwent inguinal and/or umbilical hernia repair. Patients receiving IV ibuprofen used more oxycodone/acetaminophen (32% vs 13% and IV hydromorphone (12% vs 8.7%, and fewer combinations of pain medications (44% vs 65.2% in the first two postoperative hours compared to placebo (p=0.556. The IV ibuprofen group had more patients pain free (28% vs 8.7%, p=0.087 and lower VAS scores (3.08±2.14 vs 3.95±1.54, p=0.134 at 2 hours postoperatively, compared to the placebo group, however, this was not statistically significant. Similar pain levels at 1, 3, and 7 days, postoperative and similar use of rescue

.001) while hospitalized. The average LOS for the POEM group was 31.2 h and 55.79 for the LHM group (p < 0.0001). At discharge, fewer POEM patients required a prescription for a narcotic analgesic (6.81 vs 92.4 %, p < 0.0001). POEM demonstrated significantly less postoperative pain upon arrival to the recovery room and 1 h postoperatively. To achieve similar pain scores during the first 24 h and at discharge, LHM patients required more narcotic analgesic administration. Despite a significantly shorter LOS, fewer POEM patients require a prescription for narcotic analgesics compared to LHM. POEM is a less painful procedure for achalasia than LHM, permitting earlier hospital discharge with little need for home narcotic use.

Tolerance to non-opioid analgesics is opioid-sensitive in nucleus raphe magnus

Full Text Available Repeated injection of opioid analgesics can lead to a progressive loss of its effect. This phenomenon is known as tolerance. Several lines of investigations have shown that systemic, intraperitoneal administration or the microinjection of non-opioid analgesics, non-steroidal anti-inflammatory drugs (NSAIDs in the midbrain periaqueductal gray matter induces antinociception with some effects of tolerance. Our recent study has revealed that microinjection of three drugs analgin, ketorolac and xefocam into the central nucleus of amygdala produce tolerance to them and cross-tolerance to morphine. Here we report that repeated administrations of these NSAIDs into the nucleus raphe magnus (NRM in the following four days result in progressively less antinociception, i.e. produce the development of tolerance to these drugs in mail rats. Special control experiments showed that post-treatment with μ-opioid antagonist naloxone in NRM significantly decreased antinociceptive effects of NSAIDs at the first day in behavioral tail flick reflex (TF and hot plate (HP latencies. At the second day, naloxone generally had trend effects in both TF and HP tests impeded the development of tolerance to the antinociceptive effect of non-opioid analgesics. These findings strongly support the suggestion on endogenous opioid involvement in NSAIDs antinociception and tolerance in the descending pain control system. Moreover, repeated injections of NSAIDs progressively lead to tolerance to them, cross-tolerance to morphine and the risk of a withdrawal syndrome. Therefore, these results are important for human medicine too.

Morphine sulfate and methadone hydrochloride exhibit very different half-lives but are described as having an analgesic potency of one. The use of a drug like methadone may provide prolonged and constant analgesia in the perioperative setting. This double-blinded investigation used methadone and morphine intraoperatively and measured pain scores and narcotic requirements in the first 24 hours postoperatively. Thirty American Society of Anesthesiology (ASA) patients, physical status I through III, between the ages of 18 to 65 years were scheduled for orthopedic surgery and randomly assigned to receive morphine or methadone at 0.30 mg/kg. Fifteen patients received morphine and fifteen patients received methadone. There was no significant difference between the two groups in terms of age, height, weight, and ASA status. No statistically significant difference was observed among the two groups between the amount of analgesic requirements postoperatively or in the visual analogue scale pain score.

2003-01-01

Full Text Available Aim: To determine the extent to which nurses are able to correctly identify drugs as narcotics and to ascertain their perception of the addiction potential of opiates when used for pain management. Methods: A questionnaire was administered to 86 nurses who attended palliative care workshops in India. Findings: Only morphine (95%, heroin (71% and codeine (75% were correctly identified as narcotics by the majority of participants. Imipramine (34%, diazepam (20% and phenobarbitone (39% were wrongly classified as narcotics by many nurses. Dextropropoxyphene (11%, pentazocine (21%, buprenorphine (15% were correctly classified as narcotics by fewer than half the participants. Only 14% knew that that the frequency of psychological dependence due to use of morphine for cancer pain was less than 1%.

Peptidase inhibitors reduce opiate narcotic withdrawal signs, including seizure activity, in the rat.

Pinsky, C; Dua, A K; LaBella, F S

1982-07-15

Narcotic withdrawal was precipitated by administration of naloxone in a low dose at 2 h after the final dose of morphine in a 9-day dependency-inducing schedule. Withdrawal was characterized by leaps, increased nocifensor activity and by cerebral cortical epileptiform activity, the latter not generally reported to be prominent in narcotic withdrawal. Single large doses of morphine did not provoke epileptiform activity at 2 h postinjection but did induce an acute opioid dependency wherein a moderately high dose of naloxone, ineffective in non-dependent rats, provoked upward leaping and electrocortical epileptiform activity. Pretreatment of the 9-day dependent rats with peptidase inhibitors, administered intracerebroventricularly, significantly reduced withdrawal severity including the epileptiform activity. We propose that peptidase inhibitors protect certain species of endogenous opioids and/or other neuropeptides that tend to suppress expression of the narcotic withdrawal syndrome. Furthermore, our findings suggest that epileptiform activity is a nascent form of cerebral activity hitherto largely unnoticed in narcotic withdrawal and that neuropeptides may be involved in certain epileptic states.

Octreotide: a powerful non-narcotic analgesic for ocular instillation

Full Text Available The development of alternative substances for pain treatment is necessary for patients who cannot tolerate the side effects of opioids or cannot reach an adequate analgesia with these drugs. The technique using the endo-ocular instillation of drops, 2 ml of solution containing 0.05 mg of octreotide plus 1 ml of water for injectable preparations, thus obtaining a solution containing 0.025 mg / ml of octreotide, was instilled via a precision dropping that provided 0.00119 mg / drop of octreotide. Due to characteristics of pain, we administered the doses ranging from 1 to 3 drops per eye. The absence of side effects and the simplicity of execution have prompted to consider this method with extreme interest, in order to research the drugs and routes of administration which follow more the conditions of tolerability and selectivity of effects.

Full Text Available Abstract Background Work-related injuries result in considerable morbidity, as well as social and economic costs. Pain associated with these injuries is a complex, contested topic, and narcotic analgesics (NA remain important treatment options. Factors contributing to NA utilization patterns are poorly understood. This qualitative study sought to characterize the factors contributing to NA utilization amongst injured workers from the perspectives of physicians and pharmacists. Methods The study employed concept mapping methodology, a structured process yielding a conceptual framework of participants' views on a particular topic. A visual display of the ideas/concepts generated is produced. Eligible physicians and pharmacists (n = 22 serving injured workers in the province of Ontario (Canada were recruited via purposive sampling, and participated in concept mapping activities (consisting of brainstorming, sorting, rating, and map exploration. Participants identified factors influencing NA utilization, and sorted these factors into categories (clusters. Next, they rated the factors on two scales: 'strength of influence on NA over-utilization' and 'amenability to intervention'. During follow-up focus groups, participants refined the maps and discussed the findings and their implications. Results 82 factors were sorted into 7 clusters: addiction risks, psychosocial issues, social/work environment factors, systemic-third party factors, pharmacy-related factors, treatment problems, and physician factors. These clusters were grouped into 2 overarching categories/regions on the map: patient-level factors, and healthcare/compensation system-level factors. Participants rated NA over-utilization as most influenced by patient-level factors, while system-level factors were rated as most amenable to intervention. One system-level cluster was rated highly on both scales (treatment problems - e.g. poor continuity of care, poor interprofessional communication

Full Text Available Objective: Pure analgesics are only rarely used by Italian clinicians and this holds true also for rheumatologists. This work is concerned with an evaluation of the use of analgesics in a rheumatological outpatient clinic during the period 1989-1999. Methods: The records of 1705 patients consecutively seen at the clinic were downloaded on a specifically built website. Results: 4469 visits were considered. In 260 of them (5.8%, analgesics were prescribed to 234 (13.7% patients. The number of patients with a prescription of analgesics steadily increased during the years 1989-1999. The diagnoses in patients assuming analgesics were: osteoarthritis (47.1%, inflammatory arthritis (24.2%, soft tissue rheumatisms (13.7%, nonspecific arthralgia/myalgia (7.5%, and connective tissue diseases (2.6%. Peripheral analgesics were used in 188 (82.5% patients and central analgesics were used in the remaining 40 patients (17.5%. Analgesic drugs were used mainly in degenerative joint conditions. The indications for analgesics in the 55 patients with inflammatory arthrits were: (a partial or total remission of arthritis; for this reason non-steroidal anti-inflammatory drugs were no longer required in 18 patients; (b to increase the analgesic effect of NSAIDs in 23 patients; (c contraindications to NSAIDs in 14 patients (renal failure in 2 patients, gastritis in 10, allergy and bleeding in the remaining two. Conclusions: About 14% of our outpatients were treated with analgesics with an increasing trend in the examined period. The main indications for analgesics are degenerative conditions but they can be used also in selected patients with arthritis.

To determine if race/ethnicity-based differences exist in the management of pediatric abdominal pain in emergency departments (EDs). Secondary analysis of data from the 2006-2009 National Hospital Ambulatory Medical Care Survey regarding 2298 visits by patients ≤ 21 years old who presented to EDs with abdominal pain. Main outcomes were documentation of pain score and receipt of any analgesics, analgesics for severe pain (defined as ≥ 7 on a 10-point scale), and narcotic analgesics. Secondary outcomes included diagnostic tests obtained, length of stay (LOS), 72-hour return visits, and admission. Of patient visits, 70.1% were female, 52.6% were from non-Hispanic white, 23.5% were from non-Hispanic black, 20.6% were from Hispanic, and 3.3% were from "other" racial/ethnic groups; patients' mean age was 14.5 years. Multivariate logistic regression models adjusting for confounders revealed that non-Hispanic black patients were less likely to receive any analgesic (odds ratio [OR]: 0.61; 95% confidence interval [CI]: 0.43-0.87) or a narcotic analgesic (OR: 0.38; 95% CI: 0.18-0.81) than non-Hispanic white patients (referent group). This finding was also true for non-Hispanic black and "other" race/ethnicity patients with severe pain (ORs [95% CI]: 0.43 [0.22-0.87] and 0.02 [0.00-0.19], respectively). Non-Hispanic black and Hispanic patients were more likely to have a prolonged LOS than non-Hispanic white patients (ORs [95% CI]: 1.68 [1.13-2.51] and 1.64 [1.09-2.47], respectively). No significant race/ethnicity-based disparities were identified in documentation of pain score, use of diagnostic procedures, 72-hour return visits, or hospital admissions. Race/ethnicity-based disparities exist in ED analgesic use and LOS for pediatric abdominal pain. Recognizing these disparities may help investigators eliminate inequalities in care.

New Challenges in the Narcotics World

Full Text Available The consumption of narcotics is one of the problems the international world is confronted withnowadays; its direct or indirect effects lead to the conclusion that it represents a worrying phenomenon meantto be taken into account by the international programs of co-operation. In contrast with the mature population,the younger population is much more receptive to the new, much more attracted by new experiments and,consequently, by risks. The narcotics flagellum is one of the most complex, profound and dramaticphenomena met with in the contemporary world. Narcotization is the morbid habit of repeatedly taking andusing ever higher doses of more or less toxic substances able to generate a psychological and physicaladdiction to them. Unhappily due to the lack of information, people think that the illegal substances only –heroine, marijuana, cocaine, etc. – are considered drugs. Not long ago there appeared the so-called “mixes ofethno-botanical plants” that are perfectly legal, and many consumers have replaced narcotics - as marijuana,for example - with plant mixes. According to explanations given by the Ethno-botanical ExplanatoryDictionary, ethno-biology is a branch that studies the mutual relationship between man and plant. InRomania, ethno-botanical plants are sold under the generic names of “aroma therapeutic” or “ethnobotanical”plants. The numerous researches meant to decode the molecular and biochemical structure of theseherbs, the researchers found that consumers are described as facing hallucinogenic effects caused by somesynthetic substances - cannabinoids - added by manufacturers.

Gleditsia triacanthos L. (Leguminosae) pods are used in folk medicine for pain relief as anodyne and narcotic. The objective of this study is to evaluate analgesic activity of Gleditsia triacanthos methanolic fruit extract (MEGT) and its saponin-containing fraction (SFGT). Peripheral analgesic activity was assessed using the acetic acid-induced writhing model in mice at doses of 140, 280, and 560 mg/kg and formalin test in rats at 100, 200, and 400 mg/kg doses. Central analgesic activity was evaluated using the hotplate method in rats (100, 200, and 400 mg/kg). In the writhing test, six mice groups treated with MEGT and SFGT found ED50 values 268.2 and 161.2 mg/kg, respectively, displayed a significant decrease in writhing count compared with the group treated with standard drug indomethacin (14 mg/kg). SFGT (280 and 560 mg/kg) showed 64.94 and 70.78% protection, respectively, which are more than double % protection caused by indomethacin (31.82%). In the formalin test, MEGT and SFGT (ED50 values 287.6 and 283.4 mg/kg for phase I as well as 295.1 and 290.4 mg/kg for phase II, respectively) at 400 mg/kg showed significant % inhibition in both phase I (18.86 and 52.57%) and phase II (39.36 and 44.29%) with reference to 10 mg/kg indomethacin (56.0 and 32.29%). MEGT and SFGT caused significant delay in responses in hotplate model (ED50 values 155.4 and 200.6 mg/kg, respectively) compared with that of 10 mg/kg indomethacin at 30, 60, and 120 min. Central and peripheral analgesic activities induced by Gleditsia triacanthos fruits might account for its uses in folk medicine.

Post Laparoscopic Pain Control Using Local Anesthesia through Laparoscopic Port Sites

Directory of Open Access Journals (Sweden)

Seyyed Amir Vejdan

2014-08-01

Full Text Available Background: Severe abdominal pain is not common after laparoscopic surgeries, but acute or chronic pain after operation is considerable in some patients. Post-operative Pain control after laparoscopic surgeries, is conventionally achieved using analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs and narcotics, but their administration has a lot of side effects. This study compares the efficacy and side effects of local anesthetic drugs versus conventional analgesics in post-operative pain control.Materials and Methods: This prospective investigation was conducted into two groups of patients (n=93. Group 1, as control group, was given conventional analgesics such as narcotics and NSAIDs. In investigational group, at the end of laparoscopic surgery, prior to port withdrawal, a local anesthetic mixture, a short acting (Lidocaine 2% plus a long acting (Bupivacaine 0.5% is instilled through the port lumen between the abdominal wall layers. The efficacy of both types of medications was compared to their efficacy and side effects.Results: 85% of the control group, received 5 to 20 ml Morphine for pain control while the others were controlled with trans-rectal NSAIDs. In the treatment group, the pain of 65% of the patients was controlled only by local anesthetic drugs, 30% required NSAIDs and the other 5% required narcotics administration for pain control.Conclusion: The administration of local anesthetic drugs after laparoscopic surgery is an effective method for pain control with a low complications rate and side effects of narcotics.

THE EFFECT OF ILLICIT TRADE IN NARCOTICS ON GLOBAL ECONOMY

ALASMARI Khaled

2013-07-01

Illicit markets especially those dealing with narcotics constitute grievous issues to the world’s economies, putting to test global safety, economic progress as well as security and many other aspects. Seemingly, illicit narcotics trade in the last decade – that is 2000 to 2011 underwent a significant boom, resulting from a wide spectrum of illegal drugs such as cocaine as well as heroin among many other hard drugs. In today’s global society, several concerns are emerging on the rise of illicit narcotics trade accompanied with organized crime, chiefly as major hindrances to consistent global economic progress. Apparently, some of the effects of illicit narcotics trade are that; this trade gradually turns upside down business rules, opening way for new unruly market players besides reconfiguring influence in global economics as well as politics. Surprisingly, the revenue from illegal drugs in 2011 alone was roughly 10% of the global GDP. Hence, exaggerating local economies’ incomes and triggering ceaseless conflicts among market players, while at the same time reducing legal business activities likewise disintegrating socioeconomic conditions. An empirical research method was adopted for this study, analyzing illicit trade in narcotics on the global arena as from 2000 to 2011 and its resultant effects. The research findings indicate that, illegal drugs trade particularly on the world economy besides growing at a high rate, it endangers the overall welfare of humans likewise the business environment. This is ostensibly because this trade has high chances of engrossing regional economies into illegal drugs business activities, causing them to neglect sustainable ethical businesses. Now, to effectively address negative economic issues related to illegal drugs trade, there is apparent need for integrated efforts from local as well as international authorities. Such efforts are chiefly to control not only the harmful effects resulting from the use of illicit

This paper traces the history of the narcotic clinic in New Orleans, Louisiana, comparing its merits to a similar clinic in Shreveport. How do the clinics compare, and why did the Shreveport clinic operate for longer than its New Orleans counterpart? Qualitative analysis of contemporary medical journals and newspapers, as well as archival materials from the Narcotic Division. In addition, the records of Louisiana Governor John M. Parker, the papers of Dr Willis P. Butler in Shreveport, as well as the records of the Orleans Parish Medical Society have been utilized. The narcotic clinic in Shreveport benefited from strong local support, while the New Orleans clinic faced a more vocal opposition. In addition, the Shreveport clinic offered a broad array of services and was a pillar of the community; the New Orleans clinic was newly established and offered fewer services. It was especially the influx of out-of-state addicts that angered many New Orleanians, many of whom witnessed the addicts lined up in the French Quarter. The effectiveness of the narcotic clinics in Louisiana (1919-23) was influenced by local opinion. The New Orleans clinic faced a tougher political climate than its counterpart in Shreveport, and therefore proved less resilient in the face of federal opposition. © 2017 Society for the Study of Addiction.

The prevalence of chronic non-malignant pain in Norway is between 24% and 30%. The proportion of the population using opioids for non-malignant pain on a long-term basis is around 1%. The purpose of our study was to investigate how many were prescribed analgesics on reimbursable prescription under reimbursement code -71 (chronic non-malignant pain) in 2009 and 2010, which analgesics were prescribed and whether prescribing practices were in accordance with national guidelines. We retrieved pseudonymised data from the National Prescription Database on all those who received drugs with reimbursement code -71 in 2009 and 2010. The data contain information on drug, dosage, formulation, reimbursement code and date of issue. 90,731 patients received reimbursement for drugs indicated for chronic non-malignant pain in 2010. Of these, 6,875 were given opioids, 33,242 received paracetamol, 25,865 non-steroid inflammatory drugs (NSAIDs), 20,654 amitryptiline and 16,507 gabapentin. Oxycodone was the most frequently prescribed opioid, followed by buprenorphine, tramadol and codeine/paracetamol. Of those who were prescribed opioids, 4,047 (59%) received mainly slow-release opioids, 2,631 (38%) also received benzodiazepines and 2,418 (35%) received benzodiazepine-like sleep medications. The number of patients who received analgesics and opioids on reimbursable prescriptions was low compared to the proportion of the population with chronic pain and the proportion using opioids long-term. 38% of those reimbursed for opioids also used benzodiazepines, which is contrary to official Norwegian guidelines.

Full Text Available Introduction. The incidence of cancer in recent years has increased significantly. It is therefore particularly important today is the issue of provision for patients with malignancies with drugs. It is important to research the level of organization of availability of the anesthetic therapy to ensure the availability of pharmacotherapy for cancer patients worldwide. Material and methods. For the purpose of the study analyzed legislation, regulations of some states in the US that provide availability of narcotic analgesic drugs for patients with malignant neoplasms. The paper used the following methods: comparative, documentary, legal, medical, pharmaceutical and graphical analysis. Results and discussion. Noted the increase in expenditure on pharmaceutical provision for patients with malignancies on an outpatient basis in the US. During the study of the legislative and regulatory acts of the USA found that payments for treatment possible by insurance companies as part of the agreement, which in turn depend on the patient’s age, number of family members, their total income and so on. Coupons can be used to pay for the cost of medicines, but not all pharmacies accept coupons. There are charities with funds which are partially covered for the cost of chemotherapy and adjuvant therapy (analgesics, antiemetic, antipsychotics, drugs. Found, that in New York doctor may prescribe analgesic medication to the patient without limitation in the frequency and dose. It is not therapeutic use of analgesics, their improper accounting, drug addiction patient has contraindications to the prescription of narcotic analgesic drugs with malignant neoplasms. Reviewed examples from forensic and pharmaceutical practice, pharmaceutical violation of the US laws that regulate the accessibility of patients with malignancies to narcotic analgesic drugs. So, there have been cases of fake prescriptions for narcotic drugs, selling drugs, the shelf life has expired. Police of

Bayer AG has recently announced that it acquired exclusive rights for the marketing of GW Pharmaceuticals' new medicine Sativex in Europe and in other regions. Sativex is a sublingual spray on Cannabis extract basis, and is equipped with an electronic tool to facilitate accurate dosing and to prevent misuses. It is standardized for the THC and CBD. The new analgesic is proposed for the treatment of muscle spasticity and pains accompanying multiple sclerosis and as an efficient analgetic for neurogenic pain not responding well to opioids and to other therapies available. The entirely new mechanism of action through the recently discovered cannabinoid receptor system may offer a real therapeutic potential to the drug. Although the Government of Netherlands has authorized the sale of pharmaceutical grade Cannabis herb by pharmacies in the Netherlands, the availability on the pharmaceutical market of the registered preparation may render requests for the authorization of the smoking of Cannabis herb (marihuana) by individuals suffering of multiple sclerosis, neurogenic pain, AIDS wasting syndrome unnecessary. Nevertheless, the "old chameleon" plant Cannabis appears to gradually regain its previous status in mainstream therapy and pharmacy. As long as the plant Cannabis and its products continue to be classified as narcotic drugs, medical use of the new preparation will need close supervision.

We assessed the antioxidant activity of non-narcotic analgesics, acetaminophen and aspirin in rat brain homogenates and neuroprotective effects in vivo in rats intranigrally treated with 1-methyl-4-phenyl pyridinium (MPP+). Both drugs inhibited cyanide-induced superoxide anion generation, as well as lipid peroxidation in rat brain homogenates, the combination of the agents resulting in a potentiation of this effect. Acetaminophen or aspirin when administered alone or in combination, did not alter dopamine (DA) levels in the forebrain or in the striatum. Intranigral infusion of MPP+ in rats caused severe depletion of striatal DA levels in the ipsilateral striatum in rats by the third day. Systemic post-treatment of acetaminophen afforded partial protection, whereas similar treatment of aspirin resulted in complete blockade of MPP+-induced striatal DA depletion. While these findings suggest usefulness of non-narcotic analgesics in neuroprotective therapy in neurodegenerative diseases, aspirin appears to be a potential candidate in prophylactic as well as in adjuvant therapy in Parkinson's disease.

Pain control after traumatic rib fracture is essential to avoid respiratory complications and prolonged hospitalization. Narcotics are commonly used, but adjunctive medications such as nonsteroidal anti-inflammatory drugs may be beneficial. Twenty-one patients with traumatic rib fractures treated with both narcotics and intravenous ibuprofen (IVIb) (Treatment) were retrospectively compared with 21 age- and rib fracture-matched patients who received narcotics alone (Control). Pain medication requirements over the first 7 hospital days were evaluated. Mean daily IVIb dose was 2070 ± 880 mg. Daily intravenous morphine-equivalent requirement was 19 ± 16 vs 32 ± 24 mg (P pain scores were lower in the Treatment group (P rib fractures significantly decreases narcotic requirement and results in clinically significant decreases in hospital length of stay. IVIb therapy should be initiated in patients with traumatic rib fractures to improve patient comfort and reduce narcotic requirement.

Efforts of Controlling Money Laundering of Narcotics Money in Saudi Arabia

Directory of Open Access Journals (Sweden)

Khaled A. ALASMARI

2014-06-01

Full Text Available Money laundering is a silent crime. Its goal is to cover up the source of large sums of money that criminals often gather from their criminal activities. This paper will analyze the situation of money laundering in narcotics as it applies in Saudi Arabia. To achieve this end, the paper will first define important terms such as money laundering and narcotics. It will then explain the relationship between money laundering, narcotics trade, and terrorism activities. This background information will form the base for analyzing the various efforts that the Saudi Arabia nation has in place for countering money laundering in narcotics trade. The paper will then explain the challenges facing these efforts, and the future of money laundering in Saudi Arabia. The largest criminal activity associated with money laundering is terrorism financing. The several terror attacks associated with Saudi Arabia’s terror groups like Al-Qaida have made the government realize the importance of curbing money laundering in an effort to counter terrorism. Thus, anti-money laundering strategies are set in place to address all the avenues of money laundering.

Non-analgesic effects of opioids: management of opioid-induced constipation by peripheral opioid receptor antagonists: prevention or withdrawal?

Science.gov (United States)

Holzer, Peter

2012-01-01

The therapeutic action of opioid analgesics is compromised by peripheral adverse effects among which opioid-induced constipation (OIC) is the most disabling, with a prevalence reported to vary between 15 and 90 %. Although OIC is usually treated with laxatives, there is insufficient clinical evidence that laxatives are efficacious in this indication. In contrast, there is ample evidence from double- blind, randomized and placebo-controlled trials that peripheral opioid receptor antagonists (PORAs) counteract OIC. This specific treatment modality is currently based on subcutaneous methylnaltrexone for the interruption of OIC in patients with advanced illness, and a fixed combination of oral prolonged-release naloxone with prolonged-release oxycodone for the prevention of OIC in the treatment of non-cancer and cancer pain. Both drugs counteract OIC while the analgesic effect of opioids remains unabated. The clinical studies show that more than 50 % of the patients with constipation under opioid therapy may benefit from the use of PORAs, while PORA-resistant patients are likely to suffer from non-opioid-induced constipation, the prevalence of which increases with age. While the addition of naloxone to oxycodone seems to act by preventing OIC, the intermittent dosing of methylnaltrexone every other day seems to stimulate defaecation by provoking an intestinal withdrawal response. The availability of PORAs provides a novel opportunity to specifically control OIC and other peripheral adverse effects of opioid analgesics (e.g., urinary retention and pruritus). The continuous dosing of a PORA has the advantage of few adverse effects, while intermittent dosing of a PORA can be associated with abdominal cramp-like pain.

Despite opioid analgesics being essential for pain relief, use has been inadequate in many countries. We aim to provide up-to-date worldwide, regional, and national data for changes in opioid analgesic use, and to analyse the relation of impediments to use of these medicines. We calculated defined daily doses for statistical purposes (S-DDD) per million inhabitants per day of opioid analgesics worldwide and for regions and countries from 2001 to 2013, and we used generalised estimating equation analysis to assess longitudinal change in use. We compared use data against the prevalence of some health disorders needing opioid use. We surveyed 214 countries or territories about impediments to availability of these medicines, and used regression analyses to establish the strength of associations between impediments and use. The S-DDD of opioid analgesic use more than doubled worldwide between 2001-03 and 2011-13, from 1417 S-DDD (95% CI -732 to 3565; totalling about 3.01 billion defined daily doses per annum) to 3027 S-DDD (-1162 to 7215; totalling about 7.35 billion defined daily doses per annum). Substantial increases occurred in North America (16,046 S-DDD [95% CI 4032-28,061] to 31,453 S-DDD [8121-54,785]), western and central Europe (3079 S-DDD [1274-4883] to 9320 S-DDD [3969-14,672]), and Oceania (2275 S-DDD [763-3787] to 9136 S-DDD [2508-15,765]). Countries in other regions have shown no substantial increase in use. Impediments to use included an absence of training and awareness in medical professionals, fear of dependence, restricted financial resources, issues in sourcing, cultural attitudes, fear of diversion, international trade controls, and onerous regulation. Higher number of impediments reported was significantly associated with lower use (unadjusted incidence rate ratio 0.39 [95% CI 0.29-0.52]; p<0.0001), but not when adjusted for gross domestic product and human development index (0.91 [0.73-1.14]; p=0.4271). Use of opioid analgesics has increased, but

Opioid maintenance treatments (OMT) reduce illicit opiate use and its associated risks. They are often prescribed on a long-term basis. Physiological changes induced by long-term OMT may cause hyperalgesia and cross-tolerance to opioid agonists, which suggests that the dosage of analgesic treatment should be modified in cases of acute pain, especially when an opioid-based analgesia is required. When treatment with analgesics is necessary, OMT must be maintained, except in exceptional cases. If a split-dosing schedule is temporarily employed during OMT, the daily dosage should not be increased for analgesic purposes. Analgesic treatment must be managed differently in case of treatment with buprenorphine or methadone. With buprenorphine, non-opioid analgesics should be introduced first, if possible. If this strategy is inefficient or contraindicated, a temporary or definitive switch to methadone should be considered. In the case of methadone-based OMT, opioid analgesics should be added directly and the dosage should be adapted according to the level of pain reported by the patient.

Dietz, Pavel; Dalaker, Robert; Letzel, Stephan; Ulrich, Rolf; Simon, Perikles

2016-10-01

The two major objectives of this study were (i) to assess variables that predict the use of analgesics in competitive athletes and (ii) to test whether the use of analgesics is associated with the use of doping. A questionnaire primarily addressing the use of analgesics and doping was distributed among 2,997 triathletes. Binary logistic regression analysis was performed to predict the use of analgesics. Moreover, the randomised response technique (RRT) was used to estimate the prevalence of doping in order to assess whether users of analgesics have a higher potential risk for doping than non-users. Statistical power analyses were performed to determine sample size. The bootstrap method was used to assess the statistical significance of the prevalence difference for doping between users and non-users of analgesics. Four variables from a pool of 16 variables were identified that predict the use of analgesics. These were: "version of questionnaire (English)", "gender (female)", "behaviour in case of pain (continue training)", and "hours of training per week (>12 h/week)". The 12-month prevalence estimate for the use of doping substances (overall estimate 13.0%) was significantly higher in athletes that used analgesics (20.4%) than in those athletes who did not use analgesics (12.4%). The results of this study revealed that athletes who use analgesics prior to competition may be especially prone to using doping substances. The predictors of analgesic use found in the study may be of importance to prepare education material and prevention models against the misuse of drugs in athletes.

Conventional suppositories sometimes fail in exerting their therapeutic activity as the base materials melt inside body cavities. Also they are not suitable to provide long term treatment. Biomedical grade silicone elastomers may be used to fabricate non-dissolvable suppositories to overcome these disadvantages. We kneaded 4 analgesics into the 2 kinds of silicone polymers at 1%, 5% and 10% drug loading, respectively, to test their mechanical properties and drug release profiles. The optimized drug-polymer combinations were used to fabricate suppositories, and three dimensional printing (3DP) was used to create the suppository moulds. Subsequently, the drug release profiles and biocompatibility of the suppositories were studied. It was found that, the mechanical properties of the drug laden silicone elastomers and the rate of drug release from the elastomers can be tuned by varying drug-polymer combinations. The silicone elastomers containing 1% (w/w) and 5% (w/w) diclofenac sodium were the optimal formulations with prolonged drug release and biocompatibility at cellular level. These properties, together with complex geometries offered by 3DP technique, potentially made the non-dissolving suppositories promising therapeutic agents for personalized medicine.

Choueiri, Toni K.; Je, Youjin; Cho, Eunyoung

2013-01-01

Analgesics are the most commonly used over-the-counter drugs worldwide with certain analgesics having cancer prevention effect. The evidence for an increased risk of developing kidney cancer with analgesic use is mixed. Using a meta-analysis design of available observational epidemiologic studies, we investigated the association between analgesic use and kidney cancer risk. We searched the MEDLINE and EMBASE databases to identify eligible case-control or cohort studies published in English until June 2012 for 3 categories of analgesics: acetaminophen, aspirin or other Non-Steroidal Anti-Inflammatory Drugs (NSAIDs). Study-specific effect estimates were pooled to compute an overall relative risk (RR) and its 95% confidence interval (CI) using a random effects model for each category of the analgesics. We identified 20 studies (14 with acetaminophen, 13 with aspirin, and 5 with other NSAIDs) that were performed in 6 countries, including 8,420 cases of kidney cancer. Use of acetaminophen and non-aspirin NSAIDs were associated with an increased risk of kidney cancer (pooled RR, 1.28; 95% CI, 1.15 to 1.44 and 1.25; 95% CI, 1.06 to 1.46, respectively). For aspirin use, we found no overall increased risk (pooled RR, 1.10; 95% CI, 0.95 to 1.28), except for non-US studies (5 studies, pooled RR=1.17, 95% CI, 1.04 to 1.33). Similar increases in risks were seen with higher analgesic intake. In this largest meta-analysis to date, we found that acetaminophen and non-aspirin NSAIDs are associated with a significant risk of developing kidney cancer. Further work is needed to elucidate biologic mechanisms behind these findings. PMID:23400756

Does advanced cryotherapy reduce pain and narcotic consumption after knee arthroplasty?

Science.gov (United States)

Thienpont, Emmanuel

2014-11-01

Cryotherapy has been used to enhance recovery after orthopaedic surgery. Several cooling devices are available but few can guarantee a fixed temperature during a prolonged time and therefore have been criticized. The arrival of new advanced cryotherapy devices made it possible to test the effect of prolonged cooling on rehabilitation after joint replacement. The hypotheses of this randomized controlled trial (RCT) were that advanced cryotherapy devices compared with cold packs result in (1) better postoperative pain control resulting in a lower consumption of narcotics; (2) better early ROM; and (3) less postoperative bleeding and swelling. A priori sample size calculation had determined that to detect a difference of 2 points on the VAS, a sample size of 50 subjects per group at followup would be required, given a study power of 80%. One hundred sixteen patients were included and randomly allocated to receive advanced cryotherapy (n=58) or use of cold packs (n=58). The primary outcomes for the study were to evaluate pain with the VAS and analgesics consumption. Secondary outcomes were postoperative ROM, swelling, and blood loss. One hundred (50 in each group) patients had complete data available for analysis. No statistically significant differences in VAS, need for analgesics, nor in secondary outcomes were observed, except for substantially reduced flexion at 6 weeks in the advanced cryotherapy group (114° versus 120°). Advanced cryotherapy with a continuous temperature for a prolonged period does not deliver expected results of superior early recovery after knee arthroplasty. Greater sample sizes are required to fully determine significant differences between the two techniques for these study parameters. Immobilization of the knee in extension during the prolonged cryotherapy session resulted in lower active flexion at 6 weeks after surgery for the advanced cryotherapy group. Advanced cryotherapy should not be used in fast track knee arthroplasty if the

We sought to determine perioperative patterns of narcotic use and the prevalence of postoperative doctor shopping among patients with nephrolithiasis requiring operative management. We retrospectively reviewed the records of consecutive patients residing in Tennessee who required ureteroscopy with laser lithotripsy for nephrolithiasis at a single institution from January to December 2013. Using the Tennessee CSMD (Controlled Substances Medication Database) patients were categorized by the number of postoperative narcotic providers. Doctor shopping behavior was identified as any patient seeking more than 1 narcotic provider within 3 months of surgery. Demographic and clinical characteristics associated with doctor shopping behavior were identified. During the study period 200 eligible patients underwent ureteroscopy with laser lithotripsy for nephrolithiasis, of whom 48 (24%) were prescribed narcotics by more than 1 provider after surgery. Compared to those receiving narcotics from a single provider, patients with multiple narcotic providers were younger (48.1 vs 54.2 years, p shopping is common among patients with nephrolithiasis who require operative management. Urologists should be aware of available registry data to decrease the likelihood of redundant narcotic prescribing. Copyright © 2016 American Urological Association Education and Research, Inc.

Previous studies of predictors of narcotic abuse have been retrospective and based on samples of long-term addicts obtained from legal or medical channels. There are several methodological problems in this approach. The present study is an attempt to test certain alleged predictors of narcotic use in a cohort of 898 Vietnam veterans. The design overcomes several of the methodological weaknesses of previous studies. Eight variables which have been reported as predictors of drug use or addiction in the drug literature were inquired about during a personal interview which included the premilitary life of each subject. The antecedent variables were socioeconomic background, inner city residence, psychiatric illness, broken home, race, employment history, education and antisocial history. Using information obtained from interviews and military records, we then tested the predictive value of each of these antecedents by comparing narcotic used and addiction in Vietman and use after Vietnam in men differing with respect to each antecedent. Results indicate that some of the variables were very poor, and others very good predictors of the various levels of narcotic involvement. The predictive value and overall importance of each of the variables we tested are discussed.

Study was carried out at two dose levels (270 mg/kg and 540 mg/kg) in albino rats. Analgesic activity was evaluated in formalin induced paw licking, and tail flick methods whereas indomethacin and pentazocine were used as standard analgesic drugs, respectively. At both the dose levels, test drug non-significantly decreased paw licking response at both time intervals. In tail flick model, the administration of the test drug increased pain threshold response in a dose dependent manner. In therapeutically equivalent dose level, analgesic activity was observed only after 180 min while in TED ×2 treated group analgesia was observed at 30 min and lasted even up to 240 min. The results suggested that N.canescens root possess moderate analgesic activity. PMID:24250136

Spectral features of non-opioid analgesic drug flupirtine have been explored by the Fourier transform infrared, Raman and Nuclear magnetic resonance spectroscopic techniques combined with density functional theory computations. The bioactive conformer of flupirtine is stabilized by an intramolecular Csbnd H⋯N hydrogen bonding resulting by the steric strain of hydrogen atoms. Natural bond orbital and natural population analysis support this result. The charge redistribution also has been analyzed. Antimicrobial activities of flupirtine have been screened by agar well disc diffusion and molecular docking methods, which exposes the importance of triaminopyridine in flupirtine.

Many analgesics have been withdrawn from the market because of adverse drug reactions. Controversy still surrounds the use of some approved analgesics for pain management. However, the trends and reasons for withdrawal of analgesics when harms are attributed to their use have not been systematically assessed. Areas covered: We conducted searches in PubMed; Embase; Google Scholar; clinicaltrials.gov; WHO databases of withdrawn products; websites of the European Medicines Agency, the US Food and Drug Administration, the UK Medicines and Healthcare products Regulatory Agency; Meyler's Side Effects of Drugs; Stephens' Detection of New Adverse Drug Reactions; the Pharmaceutical Manufacturing Encyclopedia; and the Merck Index. We included licensed analgesics that were withdrawn after marketing because of adverse reactions between 1950 and March 2017. We excluded herbal products, non-human medicines, and non-prescription medicines. We used the Oxford Centre for Evidence Based Medicine criteria to document the levels of evidence, and chi-squared tests to compare withdrawal patterns across geographical regions. Expert opinion: Pharmacovigilance systems in low-resource settings should be strengthened. Greater co-ordination across regulatory authorities in assessing and interpreting the benefit-harm balance of new analgesics should be encouraged. Future reporting of harms in clinical trials of analgesics should follow standardized guidelines.

Non-analgesic effects of opioids: opioids and the endocrine system.

Opioids are among the oldest known and most widely used analgesics. The application of opioids has expanded over the last few decades, especially in the treatment of chronic non-malignant pain. This upsurge in opioid use has been accompanied by the increasingly recognized occurrence of opioid-associated endocrinopathy. This may arise after exposure to enteral, parenteral, or neuraxial opioids. Opioid-associated endocrinopathy consists primarily of hypothalamic-pituitary-gonadal axis or hypothalamic-pituitary-adrenal axis dysfunction and may manifest with symptoms of hypogonadism, adrenal dysfunction, and other hormonal disturbances. Additionally, opioid related endocrine dysfunction may be coupled with such disorders as osteoporosis and mood disturbances including depression. Undesirable changes in pain sensitivity such as opioid-induced hyperalgesia, and reduced potency of opioid analgesia may also be potential consequences of chronic opioid consumption. Few studies to date have been able to establish what degree of opioid exposure, in terms of dose or duration of therapy, may predispose patients to opioid-associated endocrinopathy. This article will review the currently available literature concerning opioid-associated endocrinopathy and will provide recommendations for the evaluation, monitoring, and management of opioid-associated endocrinopathy and its other accompanying undesired effects.

Acute periradicular abscess is a condition characterized by the formation and propagation of pus in the periapical tissues and generally associated with debilitating pain. The aim of this study was to compare the overall analgesic effectiveness of two combinations of opioid and non-opioid analgesics for acute periradicular abscess. This study included 26 patients who sought emergency care in a Brazilian dental school. The patients were randomly divided into two groups: Co/Ac - oral prescription of codeine (30 mg) plus acetaminophen (500 mg), every 4 h, for 3 days or Tr/Ac - oral prescription of tramadol hydrochloride (37.5 mg) plus acetaminophen (500 mg) on the same schedule. Two factors were evaluated: (1) pain scores recorded by the patients in a pain diary 6, 12, 24, 48, and 72 h after treatment, using the Visual Analogue Scale; and (2) the occurrence of adverse effects. In both groups, there was a reduction in pain scores over time. For the Co/Ac group, there was a significant reduction in the scores 12, 24, 48, and 72 hours after treatment (P0.05), i.e., both treatments were effective in controlling pain caused by APA; however, the combination of Tr/Ac caused more adverse reactions as two patients had to stop using the medication. This study suggests that, considering both analgesic efficacy and safety, the combination of codeine and acetaminophen is more effective to control moderate to severe pain from acute periradicular abscesses.

Previous studies have shown that birth order is an important predictor of later life health as well as socioeconomic attainment. In this study, we examine the relationship between birth order and hospitalization for alcohol and narcotics use in Sweden. We study the relationship between birth order and hospitalization related to alcohol and narcotics use before and after the age of 20 using Swedish register data for cohorts born 1987-1994. We apply Cox proportional hazard models and use sibling fixed effects, eliminating confounding by factors shared by the siblings. Before age 20 we find that later born siblings are hospitalized for alcohol use at a higher rate than first-borns, and there is a monotonic increase in the hazard of hospitalization with increasing birth order. Second-borns are hospitalized at a rate 47% higher than first-borns, and third-borns at a rate 65% higher. Similar patterns are observed for hospitalization for narcotics use. After age 20 the pattern is similar, but the association is weaker. These patterns are consistent across various sibling group sizes. Later born siblings are more likely to be hospitalized for both alcohol and narcotics use in Sweden. These birth order effects are substantial in size, and larger than the estimated sex differences for the risk of hospitalization related to alcohol and drug use before age 20, and previous estimates for socioeconomic status differences in alcohol and drug abuse.

Karlsen, Anders P; Mathiesen, Ole; Dahl, Jørgen B

2018-03-01

Postoperative analgesic interventions are often tested adjunct to basic non-opioid analgesics in randomized controlled trials (RCTs). Consequently, treatment in control groups, and possible assay sensitivity, differs between trials. We hypothesized that postoperative opioid requirements and pain intensities vary between different control groups in analgesic trials. Control groups from RCTs investigating analgesic interventions after total hip and knee arthroplasty were categorized based on standardized basic analgesic treatment. Morphine consumption 0 to 24 hours postoperatively, and resting pain scores at 6 and 24 hours for subgroups of basic treatments, were compared with ANOVA. In an additional analysis, we compared pain and opioid requirements in trials where a non-steroidal anti-inflammatory drug (NSAID) was administered as an intervention with trial where NSAID was administered in a control group. We included 171 RCTs employing 28 different control groups with large variability in pain scores and opioid requirements. Four types of control groups (comprising 78 trials) were eligible for subgroup comparisons. These subgroups received "opioid" alone, "NSAID + opioid", "acetaminophen + opioid", or "NSAID + acetaminophen + opioid", respectively. Morphine consumption and pain scores varied substantially between these groups, with no consistent superior efficacy in any subgroup. Additionally, trials administering NSAID as an intervention demonstrated lower pain scores and opioid requirements than trials where NSAID was administered in a control group. Analgesic treatment in RCT control groups varies considerably. Control groups receiving various combinations of opioid, NSAID and acetaminophen did not differ consistently in pain and opioid requirements. Pain and opioid requirements were lower in trials administering NSAID as an intervention compared with trials administering NSAID in a control group.

Mycolactone, a polyketide molecule produced by Mycobacterium ulcerans , is the etiological agent of Buruli ulcer. This lipid toxin is endowed with pleiotropic effects, presents cytotoxic effects at high doses, and notably plays a pivotal role in host response upon colonization by the bacillus. Most remarkably, mycolactone displays intriguing analgesic capabilities: the toxin suppresses or alleviates the pain of the skin lesions it inflicts. We demonstrated that the analgesic capability of mycolactone was not attributable to nerve damage, but instead resulted from the triggering of a cellular pathway targeting AT₂ receptors (angiotensin II type 2 receptors; AT₂R), and leading to potassium-dependent hyperpolarization. This demonstration paves the way to new nature-inspired analgesic protocols. In this direction, we assess here the hyperpolarizing properties of mycolactone on nociceptive neurons. We developed a dedicated medium-throughput assay based on membrane potential changes, and visualized by confocal microscopy of bis-oxonol-loaded Dorsal Root Ganglion (DRG) neurons. We demonstrate that mycolactone at non-cytotoxic doses triggers the hyperpolarization of DRG neurons through AT₂R, with this action being not affected by known ligands of AT₂R. This result points towards novel AT₂R-dependent signaling pathways in DRG neurons underlying the analgesic effect of mycolactone, with the perspective for the development of new types of nature-inspired analgesics.

Full Text Available Objective: The beneficial effects of clove on toothache have been well documented. We have also previously shown the analgesic effects of clove essential oil. The present work was done to investigate the analgesic effects of the aqueous extract of clove using hot plate test. The possible role of opioid receptors in the analgesic effects of clove was also investigated using naloxone. Materials and Methods: Ninety male mice were divided into nine groups: (1 Saline, (2-4 Aaqueous (Aq 50, Aq 100, and Aq 200 groups which were treated with 50, 100, and 200 mg/kg of aqueous extract of clove, respectively, (5-7 Ethanolic (Eth 50, Eth 100, and Eth 200 groups which were treated with 50, 100, and 200 mg/kg of ethanolic extract of clove, respectively, and (8-9 Aq 100- Naloxone and Aq 200- Naloxone which were pretreated with 4 mg/kg of naloxone before injection of 100 or 200 mg/kg of the aqueous extract. The hot plate test was performed as a base record 10 min before injection of drugs and consequently repeated every 10 minutes after the injection. Results: The maximal percent effect (MPE in the animal groups treated with 50, 100, and 200 mg/kg of aqueous extract was significantly higher than the control group. Pretreatment with naloxone reduced the analgesic effects of both 100 and 200 mg/kg of the aqueous extract. Administration of all three doses of the ethanloic extract also non-significantly increased the MPE. Conclusion: The results of the present study showed that aqueous extract of clove has analgesic effect in mice demonstrated by hot plate test which is reversible by naloxone. The role of opioid system in the analgesic effect of clove might be suggested. However, more investigations are needed to elucidate the exact mechanism(s.

Possible analgesic and anti-inflammatory interactions of aspartame with opioids and NSAIDs.

Science.gov (United States)

Sharma, Sameer; Jain, N K; Kulkarni, S K

2005-06-01

The purpose of the present study was to investigate analgesic and anti-inflammatory properties of aspartame, an artificial sweetner and its combination with various opioids and NSAIDs for a possible synergistic response. The oral administration of aspartame (2-16mg/kg, po) significantly increased the pain threshold against acetic acid-induced writhes in mice. Co-administration of aspartame (2mg/kg, po) with nimesulide (2 mg/kg, po) and naproxen (5 mg/kg, po) significantly reduced acetic acid-induced writhes as compared to effects per se of individual drugs. Similarly when morphine (1 mg/kg, po) or pentazocine (1 mg/kg, po) was co-administered with aspartame it reduced the number of writhes as compared to their effects per se. Aspartame (4,8,16 mg/kg, po) significantly decreased carrageenan-induced increase in paw volume and also reversed the hyperalgesic effects in rats in combination with nimesulide (2 mg/kg, po). The study indicated that aspartame exerted analgesic and anti-inflammatory effects on its own and have a synergistic analgesic response with conventional analgesics of opioid and non-opioid type, respectively.

Increasing numbers of people are accessing medicines from the internet. This online market is poorly regulated and represents a potential threat to the health of patients and members of the public. Prescription-only analgesics, including controlled opioids, are readily available to the UK public through internet pharmacies that are easily identified by popular search engines. The majority of websites do not require the customer to possess a valid prescription for the drug. Less than half provide an online health screen to assess suitability for supply. The majority have no registered geographical location. Analgesic medicines are usually purchased at prices significantly above British National Formulary prices and are often supplied in large quantities. These findings are of particular relevance to pain-management specialists who are trying to improve the rational use of analgesic drugs. To explore the availability to the UK population of prescription-only analgesics from the internet. Websites were identified by using several keywords in the most popular internet search engines. From 2000 websites, details of 96 were entered into a database. Forty-six (48%) websites sold prescription analgesics, including seven opioids, two non-opioids and 18 nonsteroidal anti-inflammatory drugs. Thirty-five (76%) of these did not require the customer to possess a valid prescription. Prescription-only analgesics, including controlled opioids, are readily available from internet websites, often without a valid prescription.

The Analgesic Potential of Cannabinoids

Historically and anecdotally cannabinoids have been used as analgesic agents. In recent years, there has been an escalating interest in developing cannabis-derived medications to treat severe pain. This review provides an overview of the history of cannabis use in medicine, cannabinoid signaling pathways, and current data from preclinical as well as clinical studies on using cannabinoids as potential analgesic agents. Clinical and experimental studies show that cannabis-derived compounds act as anti-emetic, appetite modulating and analgesic agents. However, the efficacy of individual products is variable and dependent upon the route of administration. Since opioids are the only therapy for severe pain, analgesic ability of cannabinoids may provide a much-needed alternative to opioids. Moreover, cannabinoids act synergistically with opioids and act as opioid sparing agents, allowing lower doses and fewer side effects from chronic opioid therapy. Thus, rational use of cannabis based medications deserves serious consideration to alleviate the suffering of patients due to severe pain. PMID:20073408

Transcultural use of narcotic water lilies in ancient Egyptian and Maya drug ritual.

Emboden, W A

1981-01-01

Comparisons are made between ancient ritual uses of the flowers of Nymphaea (Nymphaeaceae) in Maya and Egyptian civilizations. Recurrent motifs encountered in the art of both of these ancient civilizations suggests that the role fo the water lily was that of a narcotic (psychodysleptic) used to mediate ecstasis among a priestly caste. Relevant literature is reviewed as are chemical data. Elements in the complex belief systems of these two civilizations need to be reinterpreted in view of the use of two water lilies as ritual narcotics. The species implicated are Nymphaea caerulea Sav., in Egypt, and N. ampla DC., among the Maya.

scrutinized in this population, but it is well documented that chronic pain patients have high rates of addiction with various types of substances. Moreover, it is well documented that these patients are at higher risk for anxious (panic disorders and phobic disorders) and depressive disorders than non abusing headache patients. Anxiety and depressive scores are related to both the chronicity of headaches, and the amount of analgesic intake. Therefore, this comorbidity is possibly related to psychoactive substance use but there is no prospective study concerning chronological link between the anxious and depressive disorders and analgesic abuse. The presence of personality disorders in these patients is poorly documented, with the exception of neuroticism, which probably reflects the anxious and depressive comorbidity. Clinical findings show that a subgroup of patients needs an hospitalisation to succeed in withdrawal. They appears likely to be dependant on several types of drugs, to present with fear of pain itself, and to present with cluster B personality disorders, whereas another subgroup is specifically dependant on one type of drug, present with fear of pain induced impairement, and present with cluster C personality disorders. Those patients, when becoming aware of dependance, succeed in withdrawal at home, without the need of an hospitalization. The analgesic medication overuse and dependance can also be considered as a maladjusted strategy to manage pain (with prevalent passive and avoidant coping strategies). More research is required focusing on psychopathological aspects of analgesic overuse and dependance, to improve withdrawal modalities and to reduce the rate of relapses.

2012-01-01

Full Text Available Background: Self-medication is defined as the use of drugs for the treatment of self-diagnosed disorders. It is influenced by factors such as education, family, society, law, availability of drugs and exposure to advertisements. This study was performed to evaluate self-medication with analgesics and its pattern among different groups of Iranian University Students. Materials and Methods: A randomized, cross-sectional, multicenter study was conducted from December 2009 to February 2010. The target population of this study was 564 students out of 10,000 students attending four medical and non-medical science universities in Qom state. Data was analyzed using SPSS version 16, and analysis was conducted with descriptive analysis procedures. Results: 76.6% of the students had used analgesics in self-medication in the previous 3 months. The frequency of analgesic use in the study period was once in 19.2% of the participants, twice in 22.2%, three times in 16.3% and more than three times in 35.5% of the participants, although 6.8% of them were not sure when they were used. Of all the respondents, 49.8% reported headache as the problem. This was the most common problem, after which came Dysmenorrhea,headache and stomach ache. Bone and joint pains were other problems that led to the use of analgesics. The most commonly used source of information for self-medication with analgesics was advice from friends and family (54.7%, previously prescribed medications (30.1%, their medical knowledge (13.3% and recommendation of a pharmacist (1.9%. Conclusion: Self-medication with analgesics is very high among Iranian students in Qom city. This could be an index for other parts of the Iranian community. Because the source of information about analgesics is inappropriate, we would recommend education courses about analgesics and self-medication on the radio and television for the entire population.

ADMINISTRATIVE AND ORGANIZATIONAL ASPECTS OF FUNCTIONING OF THE SYSTEM OF AVAILABILITY NARCOTIC AND PSYCHOTROPIC MEDICINAL PREPARATIONS FOR PATIENTS WHO NEED THEM

Directory of Open Access Journals (Sweden)

2016-01-01

Full Text Available Narcotic drugs and psychotropic substances still remain indispensable in medicine. One of the top priorities of health care is to ensure the required availability of this group of drugs. The development of an effective system which can ensure crucially important availability of narcotic and psychotropic agents to people who need them for medical purposes must rely on the identification and analysis of the nature and specificity of the problems related to them as well as the ways of solving these problems. ThePurpose of the Study was to explore the constituents of the system ensuring medicinal availability of narcotic and psychotropic agents and to identify the factors hindering the availability of this group of medicinal agents.Materials and Methods. The study involved the systematic review analysis of the scientific publications and guidance  documents regulating various aspects of activities involving the turnover of controlled drugs, and the results of surveys and interviews in which medical and pharmaceutical professionals were engaged. The study employed the methods of content analysis, logical and functional analysis, etc.Results and Discussion. The system of narcotic and psychotropic drug (NPD availability for patients who need them is currently going through reforms which have been conditioned by low accessibilty of these drugs when used for medical purposes. Those engaged in the drug supply system including medical and pharmaceutical professionals point out that excessive bureaucratization of the system of NPD supply and availability, complexity of documentation and paperwork reporting thedrug flow, costliness of these activities, and strict liability account for low availability of such drugs. To ensure the rights of the citizens to relieve pain due to diseases or medical interventions, a number of changes in the laws and regulations have been made. They have simplified the requirements for NPD

Transversus abdominis plane block (TAPb) is an analgesic adjunct used for abdominal surgical procedures. Liposomal bupivacaine (LB) demonstrates prolonged analgesic effects, up to 72 hours. We evaluated the analgesic efficacy of TAPb using LB for patients undergoing open abdominal wall reconstruction (AWR). Fifty patients undergoing AWR with TAPb using LB (TAP-group) were compared with a matched historical cohort undergoing AWR without TAPb (control group). Outcome measures included postoperative utilization of morphine equivalents, numerical rating scale pain scores, time to oral narcotics, and length of stay (LOS). Cohorts were matched demographically. No complications were associated with TAPb or LB. TAP-group evidenced significantly reduced narcotic requirements on operative day (9.5 mg vs 16.5 mg, P = .004), postoperative day (POD) 1 (26.7 mg vs 39.5 mg, P = .01) and POD2 (29.6 mg vs 40.7 mg, P = .047) and pain scores on operative day (5.1 vs 7.0, P consumption and improved pain control. TAPb allowed for earlier discontinuation of intravenous narcotics and shorter LOS. Intraoperative TAPb with LB appears to be an effective adjunct for perioperative analgesia in patients undergoing open AWR. Copyright © 2016 Elsevier Inc. All rights reserved.

Analgesic usage without any consultation with a physician is very common in Poland. It increases the risk of occurrence of the harmful effect or harmful interaction with other medicaments taken by the patient. The abuse of painkillers applies not only to opioid but also to nonopioid analgesics. The largest group of commonly available medicaments are NSAIDs. The most frequent undesirable effect of NSAIDs' is dyspepsia. Among the most dangerous, and very often the ones without any symptoms, are gastric and duodenum ulceration for which the bleeding and perforation may be the first manifestation. Each non steroidal anti-inflammatory drug taken in large doses can be a cause of analgesic nephropathy. Its deceitful course can delay the diagnosis leading to chronic kidney failure. A complex supplements, that include central acting substances, increase the risk of kidney damage, as well as physical and psychological addiction. NSAIDs can cause: the heart failure to be more severe, treatment resistant arterial hypertension, increase an effectiveness of anticoagulants or antidiabetic drugs. The problem is also that some medicaments are available without a prescription (acetylsalicylic acid, ibuprofen, acetaminophen), especially that they are ingredients of many complex supplements considered safe. Taking doses larger than therapeutic or simultaneously taking many supplements of the same active substance had many times led to poisoning and even death. Equally dangerous can be an abuse of tramadol, codeine and COX-2 inhibitors. Therefore, prudential prescription of NSAIDs, knowledge of risks related to therapy and informing the patients about their side effects, may decrease the number of patients abusing the analgesics which can lead to lowering the number of deaths caused by serious complications.

Pharmacological studies of lappaconitine. Analgesic activities.

Science.gov (United States)

Ono, M; Satoh, T

1988-07-01

The analgesic activity of lappaconitine, which is contained in the root of Aconitum sinomantanum Nakai, was examined after oral and subcutaneous administration to mice or rats by using methods for screening of analgesics, i.e., hot plate, tail immersion, tail pinch, tail pressure, acetic acid-induced writhing, bradykinin-induced flexor reflex of hind limb and Randall-Selitto methods. The results were compared with those for morphine, indometacin and acetylsalicylic acid (ASA). Analgesic activities of lappaconitine were greater than those of indometacin and ASA, but generally about 2 to 5 times less than those of morphine. However, in the rat tail immersion test, orally administered lappaconitine exhibited more potent analgesic activity than morphine; in this test, lappaconitine was almost equipotent when given orally and subcutaneously, whereas the potency of orally administered morphine was only one-twentieth of that of subcutaneously administered morphine. Like morphine, lappaconitine increased the pain threshold of the normal paw as well as that of the inflamed paw when tested by the Randall-Selitto method. The results show that lappaconitine has strong analgesic activity, and further suggest that the central nervous system may be involved in the action on the pain threshold.

Narcotic smuggling and radiography of the gastrointestinal tract

1986-01-01

The gastrointestinal tract is being used to an increasing extent as a route for smuggling narcotics. Small, swallowed packages overwrapped with condoms or other materials are usually not detected by the customs authorities. Conventional abdominal radiography may indicate foreign bodies surrounded by a characteristic thin layer of gas and located in the gastrointestinal tract. Some short case histories, and the radiologic findings in four heroin 'body packers' are presented. (orig.)

Comparison of results for morphine urinalyses by radioimmunoassay and thin-layer chromatography in a narcotic clinic setting.

Science.gov (United States)

Kokoski, R J; Jain, M

1975-03-01

Radioimmunoassay (RIA) and thin-layer chromatography (TLC) were compared for morphine detection in an actual narcotic clinic setting. A choice of urines from all those screened by TLC allowed a critical comparison as to actual use or non-use of narcotic drugs, rather than a sampling at random in which the question of possible false positives or negatives cannot be conclusively answered. Although RIA is more sensitive than TLC, its advantage is apparent only in those cases where urine specimens are difficult to obtain frequently regularly or where the use of morphine is suspected by the positive identification of quinine in urine that was morphine-negative by TLC. In a selected group of negative and positive specimens chosen without conscious bias, the two methods gave consistently similar results, indicating that the modified TLC method provided a few or no false positives or negatives if the negatives were from those cases that were not positive anytime up to 3-4 days before urine collection. We conclude that RIA can be of significant value as a supplement to a TLC screening program, without sacrificing the many advantages that TLC has to offer.

Assessment of the Impact of the Narcotics Market on the Regional Socio-Economic Development

Directory of Open Access Journals (Sweden)

Aleksey Nikolaevich Klevakin

2018-03-01

Full Text Available The article considers the market of narcotics as a part of the formal and informal economy. By narcotics, the author means psychoactive substances and plants containing them, which are banned, subject to control or non-prohibited, but have a psychophysical effect on human body. Drug-related psychoactive substances are classified according to the prohibition criterion and restrictions on a turnover with reference to the illegal (criminal or shadow economy. The author considers the illegal drug market as a latent self-organizing system of socio-economic relations of criminal and shadow nature. Such market is oriented towards the turnover of potentially illegal or dangerous psychoactive substances, which are prohibited or restricted for use in non-medical purposes. The analysis of the state and development of the drug situation on the territory of the entities of the Ural Federal District confirms the relevance of the problem of drug abuse. In recent years, the primary incidence of drug addiction and harmful drug use among the adolescents aged 15–17 have grown. Synthetic narcotics and psychotropic substances of high narcogenicity dominate in the current drug market. Over the past 5 years, the average cost of a single dose of drug remains virtually unchanged. This reflects the conditional balance of purchasing power and competition in the drug market. The disparity in the volume of seized cannabis drugs and the number of cannabinoid users observed by medical institutions suggests a high level of latency in this category of drug users. To assess the degree of negative impact of the drug market, the author proposes to use a method of calculating the socioeconomic costs of the consequences of drug addiction. The methodology is supplemented with tools for determining the number of psychoactive substances consumers on the basis of the mass of these substances withdrawn from illicit trafficking, using the concentration and recalculation coefficients

Prescription pattern of antibiotic and analgesic in endodontic treatment in Kuwaiti population: A self-administered Survey

Directory of Open Access Journals (Sweden)

Manal J Al-Maslamani

2014-01-01

Full Text Available Introduction: Surgical and non-surgical endodontic treatment of involved teeth can necessitate prescription of analgesics and antimicrobials. The literature suggests confusion amongst practitioners regarding the need for adjunctive medication, mainly during non-surgical endodontic treatment, often leading to over-prescription. Aim: The aim of this study was to determine the current clinical practice of dentists participated in this study with respect to antibiotic and analgesic prescription patterns in their endodontic treatment management in Kuwait. Materials and Methods: Prescription patterns for antibiotics and analgesics were analyzed based on the responses to self-administered questionnaire (n = 169. Information was collected based on different clinical endodontic diagnostic scenarios. Statistical analysis was performed with SPSS software version 17.0 to determine relationships between prescription patterns, age, gender, and dental qualification (specialists and general dentists. Results: Ninety-two percent of dentists prescribed analgesics for the management of endodontic pain. While 16% prescribed antibiotics for severe dental pain; 62% prescribed antibiotics for acute apical abscesses. Significantly more male dentists prescribed antibiotics for dental pain than female dentists. No significant difference was found between general dental practitioners′ and specialists′ attitude toward drug prescriptions. Amoxicillin and ibuprofen were the most commonly prescribed medications. Conclusion: While the majority of dentists appeared to prescribe antibiotics and analgesics appropriately, some did not. This research confirmed previous studies and established a need for imparting information of evidence-based prescriptions protocols for the dentists surveyed in this study in Kuwait.

Thorneman, G; Akervall, J

2000-10-01

The aim of the present prospective study was to evaluate pain treatment during the first postoperative 24 h for 40 patients (age over 18) undergoing tonsillectomy. Patients were divided into two groups: group A (n = 20) received analgesics on demand and group B (n = 20) on a regular basis. Basic pain treatment consisted of paracetamol 750 mg x 6 and diclofenac 50 mg x 3. Pain measurement was performed using a visual analogue scale (VAS): a 10 cm line with 0 cm equalling no pain and 10 cm equalling the worst pain ever felt. The following parameters were studied: VAS values, the need for rescue analgesics, intra- and postoperative bleeding, nausea and vomiting, postoperative food intake and hospital time. Only 4 of 20 (20%) patients in group B needed rescue analgesics in the postoperative ward compared with 15 of 20 (75%) in group A (p values were generally rather low in both groups. The mean value for all observed VAS values was less than 4 in both study groups. However, no significant difference in VAS values was observed between the two study groups. Our results suggest that regularly given postoperative pain treatment after tonsillectomy, starting intraoperatively with paracetamol and diclofenac, has significant advantages compared with a regimen in which patients receive analgesics only on demand.

Analgesics use and ESRD in younger age: a case-control study

Directory of Open Access Journals (Sweden)

Moehner Sabine

2007-12-01

1365 controls showed a significantly decreased risk, a tiny subgroup of extreme users with over 3.5 kg lifetime use (19 cases and 11 controls showed a significant risk increase. The detailed evaluation of 22 cases and 19 controls with over 2.5 kg lifetime use recommended by the regulatory advisors showed an impressive excess of other conditions than analgesics triggering the evolution of ESRD in cases compared with controls. Conclusion We found no clinically meaningful evidence for an increased risk of ESRD associated with use of phenacetin-free analgesics in single or combined formulation. The apparent risk increase shown in a small subgroup with extreme lifetime dose of analgesics is most likely an indirect, non-causal association. This hypothesis, however, cannot be confirmed or refuted within our case-control study. Overall, our results lend support to the mounting evidence that phenacetin-free analgesics do not induce ESRD and that the notion of "analgesic nephropathy" needs to be re-evaluated.

Prescription narcotic abuse is a significant social problem. Surplus medication following surgery is 1 source of prescription diversion. We assessed prescribing practices, consumption and disposal of prescribed narcotics after urological surgery. Surveys were administered to a 3-month consecutive sample of adult patients who underwent surgery performed by full and adjunct University of Utah Urology faculty. Surveys were performed 2 to 4 weeks postoperatively. With the exception of the investigators, prescribing physicians had no prior knowledge of the study. Data collected included perception of pain control, type and quantity of medication prescribed, quantity of leftover medication, refills needed, disposal instructions and surplus medication disposition. Overall 47% of 586 patients participated in the study. Hydrocodone was prescribed most commonly (63%), followed by oxycodone (35%), and 86% of the patients were satisfied with pain control. Of the dispensed narcotics 58% was consumed and 12% of patients requested refills. A total of 67% of patients had surplus medication from the initial prescription and 92% received no disposal instructions for surplus medication. Of those patients with leftover medication 91% kept the medication at home while 6% threw it in the trash, 2% flushed it down the toilet and less than 1% returned it to a pharmacy. Overprescription of narcotics is common and retained surplus medication presents a readily available source of opioid diversion. It appears that no entity on the prescribing or dispensing ends of prescription opioid delivery is fulfilling the responsibility to accurately educate patients on proper surplus medication disposal. Surgeons should analyze prescribing practices and consider decreasing the quantity of postoperative narcotics prescribed. Copyright © 2011 American Urological Association Education and Research, Inc.

Full Text Available The aim of this pilot study was to determine if the use of Ketorolac for donor nephrectomies could decrease the use of narcotics. Methods: This is a prospective, double blind, randomized trial involving patients undergoing nephrectomy for live donor kidney transplantation. Three arms: 1. Ketorolac 30 mg IV×1 in the OR, then ketorolac 15 mg IV every 6 h for 7 doses. 2. Ketorolac 30 mg IV×1 in the OR, then placebo IV every 6 h for 7 doses. 3. Placebo IV×1 in the OR, then placebo IV every 6 h for 7 doses. Outcomes: blood loss, mortality, renal function, cumulative narcotic use, length of hospital stay (LOS, and urinary retention. Results: There were no patient deaths, blood transfusions or renal dysfunction in any study arm. Arm 1 had less narcotic use, reduced length of stay, and reduced urinary retention than Arm 3. Conclusion: There was reduced LOS, less narcotic use and less urinary retention in the Ketorolac group (Arm 1 versus the placebo group (Arm 3. Based on these results we will proceed with a larger study to compare the use of non-opioid analgesics in donor nephrectomies.

Buprenorphine and carprofen, 2 of the most commonly used analgesics in mice, must be administered every 8 to 12 h to provide sustained analgesia. Sustained-release (SR) formulations of analgesics maintain plasma levels that should be sufficient to provide sustained analgesia yet require less frequent dosing and thus less handling of and stress to the animals. The pharmacokinetics of SR formulations of buprenorphine (Bup-SR), butorphanol (Butp-SR), fentanyl (Fent-SR), carprofen (Carp-SR), and meloxicam (Melox-SR) were evaluated in mice over 72 h and compared with those of traditional, nonSR formulations. Bup-SR provided plasma drug levels greater than the therapeutic level for the first 24 to 48 h after administration, but plasma levels of Bup-HCl fell below the therapeutic level by 4 h. Fent-SR maintained plasma levels greater than reported therapeutic levels for 12 h. Therapeutic levels of the remaining drugs are unknown, but Carp-SR provided plasma drug levels similar to those of Carp for the first 24 h after administration, whereas Melox-SR had greater plasma levels than did Melox for the first 8 h. Butp-SR provided detectable plasma drug levels for the first 24 h, with a dramatic decrease over the first 4 h. These results indicate that Bup-SR provides a stable plasma drug level adequate for analgesia for 24 to 48 h after administration, whereas Carp-SR, Melox-SR, Fent-SR, and Butp-SR would require additional doses to provide analgesic plasma levels beyond 24 h in mice.

Anti-inflammatory, analgesic, and anti-pyretic activities of orally administered etofenamate, the diethylene glycol ester of flufenamic acid, were investigated in experimental animals. Against acetic acid-induced vascular permeability in mice and ultra-violet light-induced erythema in guinea pigs, etofenamate produced a dose related inhibition at doses of 40--320 mg/kg and 5--20 mg/kg, respectively. In rats, felt-pellet-induced granuloma formation and adjuvant-induced arthritis were significantly inhibited by repeated administration of etofenamate at doses of 20 mg/kg/day for 5 days and 40 mg/kg/day for 21 days, respectively. Etofenamate showed an inhibitory activity on the squeak response caused by flexing and extending the silver nitrate-induced arthritic joint in rats; and it produced a dose related anti-writhing activity at doses of 50--300 mg/kg and 10--80 mg/kg in mice and rats, respectively, in the acetic acid-induced writhing test. Etofenamate showed a significant anti-pyretic activity at doses of 0.2 mg/kg or more. These potencies of etofenamate were 0.5 to 1.6 times those of flufenamic acid. In particular, the anti-erythema, anti-arthritis, and anti-pyretic activities of etofenamate were approximately equivalent to or superior to those of flufenamic acid. From these results, it was suggested that etofenamate given orally, like other non-steroidal anti-inflammatory drugs, showed anti-inflammatory, analgesic, and anti-pyretic activities in experimental animals.

Full Text Available Background: Tonsillectomy is one of the most commonly performed surgical prcedures in childhood. Acute pain after tonsillectomy and adenoidectomy can be treated with non-opioid and opioid analgesics. Our hypothesis stated that tramadol iv after induction of anaesthesia has superior analgesic effect compared to acetaminophen.Methods:  In a prospective, randomised study we compared analgesic efficacy of tramadol (group T: 2 mg/kgBW iv and acetaminophen (group A: elixir 15 mg/kgBW before op. procedure in a group of 108 children (age 3-7 years. Exclusion critheria: allergy, liver or kidney failure, epilepsy, febrile convulsions. A standard anaesthetic technique was used: propofol, alfentanil, vecuronium, positive pressure ventilation with 60% nitrous oxide in oxygen. After the procedure each child received acetaminophen suppositories (10 mg/kgBW/4-6h and combined suppositories. Monitoring: vital signs during and after op. procedure, pain intensity on the ward (facial pain score.    Results: There were no significant differences between the two groups in age distribution (mean age 5,2 years, ASA physical status, body weight, operative procedure, pain scores (VAS 6h after operative procedure; group T: 4,21±1,45; group A: 4,06±1,33, oxygen saturation, pulse frequency and the consumption of acetaminophen suppositories. Significant difference was in the consumption of combined suppositories (group T: 1,85±0,79; group A: 1,43±0,69, p=0,003.   Conclusion: Our study has shown, that tramadol is not a superior analgesic for the relief of posttonsillectomy pain in children compared to acetaminophen.

2016-11-01

Due to the chemical structural diversity and various analgesic mechanisms, an increasing number of studies indicated that some flavonoids from medicinal plants could be promising candidates for new natural analgesic drugs, which attract high interests of advanced users and academic researchers. The aim of this systematic review is to report flavonoids and its derivatives as new analgesic candidates based on the pharmacological evidences. Sixty-four papers were found concerning the potential analgesic activity of 46 flavonoids. In this case, the evidence for analgesic activity of flavonoids and total flavonoids was investigated. Meanwhile, the corresponding analgesic mechanism of flavonoids was discussed by generalizing and analyzing the current publications. Based on this review, the conclusion can be drawn that some flavonoids are promising candidates for painful conditions and deserve particular attention in further research and development. © 2016 Wiley-VHCA AG, Zurich, Switzerland.

1997-08-01

This project was supported by LDRD funding for the development and preliminary testing of a portable narcotics detection system. The system developed combines a commercial trace detector known as an ion mobility spectrometer (IMS) with a preconcentrator originally designed by Department 5848 for the collection of explosives molecules. The detector and preconcentrator were combined along with all necessary accessories onto a push cart, thus yielding a fully portable detection unit. Preliminary testing with both explosives and narcotics molecules shown that the system is operational, and that it can successfully detect drugs as marijuana, methamphetamine (speed), and cocaine based on their characteristics IMS signatures.

Closed to reason: time for accountability for the International Narcotic Control Board

Small Dan

2007-05-01

Full Text Available Abstract For more than two decades, the International Narcotic Control Board (INCB has tried to stop harm reduction and its HIV prevention programs. This posture is based on a fundamental misunderstanding of their responsibilities and of drug addiction itself – i.e. as a public health and clinical care matter made criminal by decree. A recent focal point for the Board's action has been rejecting the use of supervised injection facilities to reduce morbidity and mortality of drug injectors. They single out individual countries and attempt to bully them into rejecting such programs under the banner of the United Nations (falsely and in the name of international treaties. Their unrelenting and unjustified badgering of signatories to the international treaties that established the INCB is not only unjustified; it is an affront to one of the core purposes of the Board itself: to ensure adequate medical supplies and safe use of controlled substances. The INCB's ill-conceived obsession with intravenousaddiction as a crime flies in the face of the medical view and policies of the World Health Organization and the universally endorsed principles of the General Assembly of the United Nations. The latest target of the INCB is North America's only supervised injection facility, Insite, located in the inner city of Vancouver, Canada. Using the power of their office to meddle in matters of public health for individual nations is without medical, scientific or legal justification. But, most importantly, it is a matter of lifeand death for these most marginalized of citizens. The empirical evidence remains that a significant portion of the continued growth of the AIDS pandemic is due to injecting drug use, and the INCB's intrusion will inevitably result in additional deaths due to preventable HIV infections and drug overdoses. So we are very pleased to call to our readers' attention to a recent report produced by the Canadian HIV/AIDS Legal Network and the

Full Text Available Introduction. This study aimed to determine if preoperative psychological tests combined with simple pain prediction ratings could predict pain intensity and analgesic usage following cesarean delivery (CD. Methods. 50 healthy women undergoing scheduled CD with spinal anesthesia comprised the prospective study cohort. Preoperative predictors included 4 validated psychological questionnaires (Anxiety Sensitivity Index (ASI, Fear of Pain (FPQ, Pain Catastrophizing Scale, and Eysenck Personality Questionnaire and 3 simple ratings: expected postoperative pain (0–10, anticipated analgesic threshold (0–10, and perceived analgesic needs (0–10. Postoperative outcome measures included post-CD pain (combined rest and movement and opioid used for the 48-hour study period. Results. Bivariate correlations were significant with expected pain and opioid usage (r=0.349, anticipated analgesic threshold and post-CD pain (r=-0.349, and perceived analgesic needs and post-CD pain (r=0.313. Multiple linear regression analysis found that expected postoperative pain and anticipated analgesic needs contributed to post-CD pain prediction modeling (R2=0.443, p<0.0001; expected postoperative pain, ASI, and FPQ were associated with opioid usage (R2=0.421, p<0.0001. Conclusion. Preoperative psychological tests combined with simple pain prediction ratings accounted for 44% and 42% of pain and analgesic use variance, respectively. Preoperatively determined expected postoperative pain and perceived analgesic needs appear to be useful predictors for post-CD pain and analgesic requirements.

2013-05-01

Impulsivity and sensation seeking have been associated with substance use disorders, including opioid use disorders. This pilot study sought to examine whether impulsivity and sensation seeking, as measured by the Barratt Impulsiveness Scale (BIS) and Sensation Seeking Scale (SSS), were associated with opioid analgesic misuse risk in chronic, low-back pain patients prescribed opioid analgesics. Participants were 42 chronic, low-back pain patients enrolled in a larger study examining problematic opioid analgesic use. Impulsivity was assessed using the BIS, sensation seeking was measured using the SSS, and opioid analgesic misuse risk was assessed using the Current Opioid Misuse Measure (COMM). Significant bivariate associations were found between the COMM and the following predictor variables: age and the three BIS subscales: Attentional Impulsiveness, Non-planning Impulsiveness, and Motor Impulsiveness. Using a multivariate linear regression, after controlling for age, the BIS subscales accounted for 29.0% of the variance in the COMM. Attentional Impulsiveness was the only significant BIS subscale. These results suggest a potential relationship between impulsivity, but not sensation seeking, and risk for opioid analgesic misuse. Impulsivity is not a prominent trait observed in chronic pain patients; however, it may be an important risk factor for opioid analgesic misuse for a subset of individuals with chronic pain. As such, these findings suggest that additional exploration of this potential risk factor is warranted. Published by Elsevier Ltd.

Routes of abuse of prescription opioid analgesics: a review and assessment of the potential impact of abuse-deterrent formulations.

Science.gov (United States)

Gasior, Maciej; Bond, Mary; Malamut, Richard

2016-01-01

Prescription opioid analgesics are an important treatment option for patients with chronic pain; however, misuse, abuse and diversion of these medications are a major global public health concern. Prescription opioid analgesics can be abused via intended and non-intended routes of administration, both intact or after manipulation of the original formulation to alter the drug-delivery characteristics. Available data indicate that ingestion (with or without manipulation of the prescribed formulation) is the most prevalent route of abuse, followed by inhalation (snorting, smoking and vaping) and injection. However, reported routes of abuse vary considerably between different formulations. A number of factors have been identified that appear to be associated with non-oral routes of abuse, including a longer duration of abuse, younger age, male sex and a rural or socially deprived location. The development of abuse-deterrent formulations of prescription opioid analgesics is an important step toward reducing abuse of these medications. Available abuse-deterrent formulations aim to hinder extraction of the active ingredient, prevent administration through alternative routes and/or make abuse of the manipulated product less attractive, less rewarding or even aversive. There are currently five opioid analgesics with a Food and Drug Administration abuse-deterrent label, and a number of other products are under review. A growing body of evidence suggests that introduction of abuse-deterrent opioid analgesics in the USA has been associated with decreased rates of abuse of these formulations. The availability of abuse-deterrent formulations therefore appears to represent an important step toward curbing the epidemic of abuse of prescription opioid analgesics, while ensuring the availability of effective pain medications for patients with legitimate medical need.

Valber da Silva Frutuoso

2007-02-01

Full Text Available Rheedia longifolia Planch et Triana belongs to the Clusiaceae family. This plant is widely distributed in Brazil, but its chemical and pharmacological properties have not yet been studied. We report here that leaves aqueous extract of R. longifolia (LAE shows analgesic and anti-inflammatory effects. Oral or intraperitoneal administration of this extract dose-dependently inhibited the abdominal constrictions induced by acetic acid in mice. The analgesic effect and the duration of action were similar to those observed with sodium diclofenac, a classical non-steroidal analgesic. In addition to the effect seen in the abdominal constriction model, LAE was also able to inhibit the hyperalgesia induced by lipopolysaccharide from gram-negative bacteria (LPS in rats. We also found that R. longifolia LAE inhibited an inflammatory reaction induced by LPS in the pleural cavity of mice. Acute toxicity was evaluated in mice treated with the extract for seven days with 50 mg/kg/day. Neither death, nor alterations in weight, blood leukocyte counts or hematocrit were noted. Our results suggest that aqueous extract from R. longifolia leaves has analgesic and anti-inflammatory activity with minimal toxicity and are therefore endowed with a potential for pharmacological control of pain and inflammation.

Can quantitative sensory testing predict responses to analgesic treatment?

Science.gov (United States)

Grosen, K; Fischer, I W D; Olesen, A E; Drewes, A M

2013-10-01

The role of quantitative sensory testing (QST) in prediction of analgesic effect in humans is scarcely investigated. This updated review assesses the effectiveness in predicting analgesic effects in healthy volunteers, surgical patients and patients with chronic pain. A systematic review of English written, peer-reviewed articles was conducted using PubMed and Embase (1980-2013). Additional studies were identified by chain searching. Search terms included 'quantitative sensory testing', 'sensory testing' and 'analgesics'. Studies on the relationship between QST and response to analgesic treatment in human adults were included. Appraisal of the methodological quality of the included studies was based on evaluative criteria for prognostic studies. Fourteen studies (including 720 individuals) met the inclusion criteria. Significant correlations were observed between responses to analgesics and several QST parameters including (1) heat pain threshold in experimental human pain, (2) electrical and heat pain thresholds, pressure pain tolerance and suprathreshold heat pain in surgical patients, and (3) electrical and heat pain threshold and conditioned pain modulation in patients with chronic pain. Heterogeneity among studies was observed especially with regard to application of QST and type and use of analgesics. Although promising, the current evidence is not sufficiently robust to recommend the use of any specific QST parameter in predicting analgesic response. Future studies should focus on a range of different experimental pain modalities rather than a single static pain stimulation paradigm. © 2013 European Federation of International Association for the Study of Pain Chapters.

Immigration within European Union – Does health immigration make a difference in analgesic use?

Directory of Open Access Journals (Sweden)

Airaksinen M.

2006-12-01

Full Text Available European integration has facilitated the emigration inside Europe and it has been predicted that the amount of immigrants in Southern European countries will increase in the future. As these people age and their morbidity increases, they will demand more services from local health care than immigrants do at the moment. The aim of this study is to determine the amount of Finnish people who have moved to Spain for health reasons (health immigrants and whether their health service and analgesic usage patterns differed from those of non-health immigrants. Methods: This study was carried out among Finnish people living in Costa del Sol area, southern Spain. The data were collected by questionnaire during 2002 by using a convenience sample of 1,000 Finns living permanently in the area (response rate 53%, n=530. Statistical analyses were conducted using statistical software SPSS 11.5.Results: Two-thirds of the respondents were categorised as health immigrants. Health immigrants were more often suffering from chronic morbidity, their perceived health status was poorer and they used public health services more often than the non-health immigrants. Half (50% of the all respondents had used some analgesics during the two weeks before the survey. There were more analgesic users among the health immigrant group (54 % vs. 43 %, p = 0.034 and they also used analgesics more frequently than the non-health immigrants (27 % vs. 9 %, p= 0.020. Conclusions: Our study indicates, that high amount of Finnish immigrants suffer from some degree of health problems and the health state factors have a large influence on the emigration into Spain. As this kind of trend might also exist among immigrants from other EU-nations, immigrants might burden the local Spanish health care services in the future. Therefore the Providers of health care services in immigrant areas should consider these trends in planning health care in the future.

Debates about the suspected association between kidney disease and use of analgesics have led to concern about whether caffeine could stimulate an undesirable overuse of phenacetin-free combined analgesics. A committee was asked to critically review the pertinent literature and to suggest guides for clinical practice and for consideration of international regulatory authorities. A group of international scientists, jointly selected by the regulatory authorities of Germany, Switzerland, and Austria and the pharmaceutical industry. All invited experts evaluated relevant literature and reports and added further information and comments. Caffeine has a synergistic effectiveness with analgesics. Although caffeine has a dependence potential, the potential is low. Experimental data regarding dependence potential for caffeine alone may not correspond to the conditions in patients with pain. Withdrawal is not likely to cause stimulation or sustainment of analgesic intake. For drug-induced headache, no single or combined analgesic was consistently identified as causative, and no evidence exists for a special role of caffeine. Strong dependence behavior was observed only in patients using phenacetin-containing preparations, coformulated with antipyretics/analgesics and caffeine. This finding may have led to the impression that caffeine stimulates overuse of analgesics. Although more experimental and long-term data would be desirable to show possible mechanisms of dependence and to offer unequivocal proof of safety, the committee concluded that the available evidence does not support the claim that analgesics coformulated with caffeine, in the absence of phenacetin, stimulate or sustain overuse.

2010-01-01

Through a cooperative effort between the U. S. Department of Energy and the Russian Federation (RF) Ministry of Defense (MOD) a Personnel Reliability Program (PRP) for the nuclear handlers within the RF MOD has been implemented. A key element in the RF MOD PRP is the detection and confirmation of narcotic use in subject military and civilian personnel. This paper describes the process of narcotics screening and testing in the RF MOD and explains the confirmation process once screening has shown a positive result. Issues of laboratory certification, employee certification, employee training, sample chain-of-custody, and equipment needs will be addressed.

The extraction of lower wisdom teeth is often performed under general anesthesia in patients with intellectual disabilities. However, the choice of analgesics has not yet been investigated. To analyze the use of analgesics during general anesthesia for extraction including lower wisdom teeth in patients with intellectual disabilities. This research is a retrospective observational study. The study population was composed of all patients presenting for extraction of lower wisdom teeth under ambulatory general anesthesia in the clinic of Special Needs Dentistry in Okayama University Hospital from April 2011 to March 2016. The distribution of the combination of analgesics and the relationship between the use of analgesics and the type of extraction were investigated. One hundred and twelve cases were enrolled in this study. Intravenous injections of flurbiprofen, acetaminophen and betamethasone were used in 96 (85.7%), 12 (10.7%) and 26 cases (23.2%), respectively. Flurbiprofen is a non-steroid anti-inflammatory drugs (NSAIDs). Acetaminophen is an old analgesic, but an injection of acetaminophen is new, which was released in 2013 in Japan. And betamethasone is not an analgesic, but a steroid. Betamethasone was used in combination with other analgesics, and was used at a higher dose in a case in which four wisdom teeth were extracted. Flurbiprofen was the main analgesic used for extraction of wisdom teeth under general anesthesia in patients with intellectual disabilities. Betamethasone was used to support flurbiprofen or acetaminophen for extractions of multiple wisdom teeth, with the aim of controlling swelling rather than relieving pain.

Full Text Available After the Second World War the United Nations (UN assumed the role of the League of Nations in formulating and operating the international regulatory framework for narcotic drugs. It gathered masses of information from across countries and continents while acting as both a forum and an agent for the emergence of agreed approaches to a heterodox array of substances. This article will examine the story of the inclusion of cannabis in the 1961 Single Convention on Narcotic Drugs. It will argue that in the years after 1945, it was officials at the UN and the WHO that played crucial roles in shaping opinions of the drug and in securing its place in the Convention.

As opioid analgesic consumption has grown, so have opioid use disorder and opioid-related overdoses. Reducing the quantity of opioid analgesics prescribed for acute non-cancer pain can potentially reduce risks to the individual receiving the prescription and to others who might unintentionally or intentionally consume any leftover tablets. Reducing the default dispense quantity for new opioid analgesic prescriptions in the electronic health record (EHR) is a promising intervention to reduce prescribing. This study is a prospective cluster randomised controlled trial with two parallel arms. Primary care sites (n=32) and emergency departments (n=4) will be randomised in matched pairs to either a modification of the EHR so that new opioid analgesic prescriptions default to a dispense quantity of 10 tablets (intervention) or to no EHR change (control). The dispense quantity will remain fully modifiable by providers in both arms. From 6 months preintervention to 18 months postintervention, patient-level data will be analysed (ie, the patient is the unit of inference). Patient eligibility criteria are: (A) received a new opioid analgesic prescription, defined as no other opioid analgesic prescription in the prior 6 months; (B) age ≥18 years; and (C) no cancer diagnosis within 1 year prior to the new opioid analgesic prescription. The primary outcome will be the quantity of opioid analgesics prescribed in the initial prescription. Secondary outcomes will include opioid analgesic reorders and health service utilisation within 30 days after the initial prescription. Outcomes will be compared between study arms using a difference-in-differences analysis. This study has been approved by the Montefiore Medical Center/Albert Einstein College of Medicine Institutional Review Board with a waiver of informed consent (2016-6036) and is registered on ClinicalTrials.gov (NCT03003832, 6 December 2016).

Full Text Available The Chir Pine, Pinus roxburghii, named after William Roxburgh, is a pine native to the Himalaya. Pinus roxburghii Sarg. (Pinaceae is traditionally used for several medicinal purposes in India. As the oil of the plant is extensively used in number of herbal preparation for curing inflammatory disorders, the present study was undertaken to assess analgesic and anti-inflammatory activities of its bark extract. Dried and crushed leaves of Pinus roxburghii Sarg. were defatted with petroleum ether and then extracted with alcohol. The alcoholic extract at the doses of 100 mg/kg, 300 mg/kg, and 500 mg/kg body weight was subjected to evaluation of analgesic and anti-inflammatory activities in experimental animal models. Analgesic activity was evaluated by acetic acid-induced writhing and tail immersion tests in Swiss albino mice; acute and chronic anti-inflammatory activity was evaluated by carrageenan-induced paw oedema and cotton pellet granuloma in Wistar albino rats. Diclofenac sodium and indomethacin were employed as reference drugs for analgesic and anti-inflammatory studies, respectively. In the present study, the alcoholic bark extract of Pinus roxburghii Sarg. demonstrated significant analgesic and anti-inflammatory activities in the tested models.

Few studies have investigated the drug utilization patterns and factors predicting drug use in pregnant women with migraine. This longitudinal drug utilization study aimed to describe patterns of analgesic use in a sample of Norwegian pregnant women according to their migraine history, and to identify predictors for analgesic use among these women. Pregnant women giving birth at Akershus University Hospital between 2008 and 2010 were recruited at ultrasound examination in gestational week 17. Data were collected by questionnaires in gestational weeks 17 and 32, and at 8 weeks postpartum, and linked to birth records. Women were grouped into four categories according to migraine history: no migraine history, previous migraine history, recent migraine history (within 1 year prior to pregnancy) and migraine in pregnancy. Patterns of use of analgesics were analyzed descriptively. Multivariable logistic regression was used to identify factors predicting analgesic use. Out of 1981 women, 5.0% reported having migraine in pregnancy, 13.2% had a recent history of migraine, 11.5% had a previous history of migraine, and 68.8% reported no history of migraine. Analgesic use declined during pregnancy. Many women switched from triptans and non-steroidal anti-inflammatory drugs to paracetamol, which constituted most of the analgesic use. Factors associated with analgesic use included recent migraine history (OR 1.6, 95% CI 1.2-2.2), more severe headache intensity (OR 1.3, 95% CI 1.3-1.4), smoking (OR 1.9, 95% CI 1.1-3.3) and multiparity (OR 1.4, 95% CI 1.1-1.7). Women with migraine stop or switch medications during pregnancy. Analgesic use in pregnancy is affected by migraine characteristics and intensity, and also by socio-demographic factors. Clinicians should bear this in mind when giving advice on adequate management of migraine in pregnancy and safe analgesic use.

The total mass attenuation coefficients (μ/ρ), total molecular (σt,m), atomic (σt,a) and electronic (σt,e) cross sections, effective atomic numbers (Zeff) and electron density (NE) were computed in the wide energy region from 1 keV to 100 GeV for the selected narcotic drugs such as morphine, heroin, cocaine, ecstasy and cannabis. The changes of μ/ρ, σt,m, σt,a, σt,e, Zeff and NE with photon energy for total photon interaction shows the dominance of different interaction process in different energy regions. The variations of μ/ρ, σt,m, σt,a, σt,e, Zeff and NE depend on the atom number, photon energy and chemical composition of narcotic drugs. Also, these parameters change with number of elements, the range of atomic numbers in narcotic drugs and total molecular weight. These data can be useful in the field of forensic sciences and medical diagnostic.

2006-01-01

This article examines the prescribing practices for peripherally acting and centrally acting analgesics, corticosteroids, and antibiotics following third molar extraction. A nationwide survey involving the prescribing patterns of a random national sample of 850 practicing oral surgeons was performed in 2004. Ibuprofen was the peripherally acting analgesic respondents used most frequently in the previous month, selected by 73.5% of the respondents. The ibuprofen dose prescribed most frequently was 800 mg, followed by doses of 600 mg and 400 mg. The centrally acting analgesic prescribed most frequently was the combination formulation of hydrocodone with acetaminophen, selected by 64.0% of the respondents. Recommendations for oral analgesics to manage postoperative pain relied on the peripherally acting analgesic ibuprofen or the centrally acting analgesic combination formulation hydrocodone with acetaminophen. Routine instructions to use centrally acting analgesics "as needed for pain" suggest that centrally acting analgesics are offered to manage pain that postoperative peripherally acting analgesics and intraoperative long-acting local anesthetics do not control adequately. The frequency with which oral and maxillofacial surgeons administered antibiotics and corticosteroids varied widely based on perceived patient need and dentist expectations.

Perianayagam, James B; Sharma, S K; Joseph, Aney; Christina, A J M

2004-11-01

The present study was designed to investigate the anti-pyretic and analgesic activity of ethanol (EEO) and aqueous (AEO) extracts of Emblica officinalis fruits in several experimental models. A single oral dose of EEO and AEO (500 mg/kg, i.p.) showed significant reduction in brewer's yeast induced hyperthermia in rats. EEO and AEO also elicited pronounced inhibitory effect on acetic acid-induced writhing response in mice in the analgesic test. Both, EEO and AEO did not show any significant analgesic activity in the tail-immersion test. These findings suggest that extracts of Emblica officinalis fruits possessed potent anti-pyretic and analgesic activity. Preliminary phytochemical screening of the extracts showed the presence of alkaloids, tannins, phenolic compounds, carbohydrates and amino acids, which may be responsible for anti-pyretic and analgesic activities.

Andersen, Lars Peter Holst

2016-10-01

The hormone, melatonin is produced with circadian rhythm by the pineal gland in humans. The melatonin rhythm provides an endogenous synchronizer, modulating e.g. blood pressure, body temperature, cortisol rhythm, sleep-awake-cycle, immune function and anti-oxidative defence. Interestingly, a number of experimental animal studies demonstrate significant dose-dependent anti-nociceptive effects of exogenous melatonin. Similarly, recent experimental- and clinical studies in humans indicate significant analgesic effects. In study I, we systematically reviewed all randomized studies investigating clinical effects of perioperative melatonin. Meta-analyses demonstrated significant analgesic and anxiolytic effects of melatonin in surgical patients, equating reductions of 20 mm and 19 mm, respectively on a VAS, compared with placebo. Profound heterogeneity between the included studies was, however, present. In study II, we aimed to investigate the analgesic, anti-hyperalgesic and anti-inflammatory effects of exogenous melatonin in a validated human inflammatory pain model, the human burn model. The study was performed as a randomized, double blind placebo-controlled crossover study. Primary outcomes were pain during the burn injury and areas of secondary hyperalgesia. No significant effects of exogenous melatonin were observed with respect to primary or secondary outcomes, compared to placebo. Study III and IV estimated the pharmacokinetic variables of exogenous melatonin. Oral melatonin demonstrated a t max value of 41 minutes. Bioavailability of oral melatonin was only 3%. Elimination t 1/2 were approximately 45 minutes following both oral and intravenous administration, respectively. High-dose intravenous melatonin was not associated with increased sedation, in terms of simple reaction times, compared to placebo. Similarly, no other adverse effects were reported. In Study V, we aimed to re-analyse data obtained from a randomized analgesic drug trial by a selection of

Transversus abdominis plane (TAP) blocks are increasingly being utilized in microvascular breast reconstruction. The implications of TAP blocks on specific reconstructive, patient and institutional outcomes remain to be fully elucidated. Patients undergoing abdominally-based microvascular breast reconstruction from 2015-2017 were reviewed. Length of stay, complications, narcotic consumption, donor-site pain and hospital expenses were compared between patients that did and those that did not receive TAP blocks with liposomal bupivacaine. Outcomes were subsequently compared in patients with elevated body mass index (BMI). Fifty patients (43.9%) received TAP blocks (27 [54.0%] under ultrasound guidance) and 64 patients (56.1%) did not. Patients with TAP blocks had significantly decreased oral and total narcotic consumption (p=0.0001 and pconsumption and postoperative pain compared to patients without TAP blocks. Patients with BMIconsumption or length of stay between the TAP versus no TAP block groups. TAP blocks with liposomal bupivacaine significantly reduce oral and total postoperative narcotic consumption as well as donor-site pain in all patients after abdominally-based microvascular breast reconstruction without increasing hospital expenses. TAP blocks additionally significantly decrease length of stay in patients with BMI≥25.

The aim of the study was to assess color perception in the Farnsworth-Munsell 100-Hue test in individuals addicted to narcotic substances, and to analyze the acquired color vision disorders, depending on the duration of addiction and abstinence. Ninety-five persons were qualified for the study. All the subjects were divided into 3 groups. Group I (drug addicts) comprised 45 individuals addicted to narcotic substances and nicotine. Group II (smokers) consisted of 30 individuals addicted only to nicotine, and group III (abstinents) included 20 individuals free of addictions. In all the study groups anamnesis, survey, standard ophthalmological examination and the Farnsworth-Munsell 100-Hue test were performed. In the Farnsworth-Munsell 100-Hue test the mean values of total error score (TES) for the purposes of the analysis, expressed in the values of square root (√TES), proved to be significantly higher in group I than in the two other groups (p colors. The Farnsworth-Munsell 100-Hue test proved useful in the detection and assessment of acquired dyschromatopsy induced by narcotic substances. The observed disorders appeared to be dependent on the duration of addiction and abstinence. Med Pr 2016;67(6):777-785.

We aimed to study phytochemical screening and analgesic activity of ethanol extract of Oroxylum indicum. The dried powder of the barks of the plant was extracted with 95% ethanol and was subjected to various phytochemical tests to ascertain the principle constituents contained in the extract. The result revealed the presence of alkaloids, flavonoids, tannins, glycosides in the ethanol extract of Oroxylum indicum. The extract was screened for analgesic activity by using hot plate, acetic acid-induced writhing and formalin test. The ethanol extract of the plant at two different doses (250 and 500 mg/kg) showed significant (Panalgesic effect in all test methods (hot plate, acetic acid-induced writhing and formalin). The analgesic activity was compared with a standard drug (ketorolac at 10 mg/kg). Based on the present findings and previous literature review it can be concluded that flavonoids and tannins might be responsible for the analgesic activity. We suggest that ethanol extract of Oroxylum indicum might have potential chemical constituents that could be used in the future for the development of novel analgesic agent.

Objective To describe psychotropic medication administration patterns during inpatient rehabilitation for traumatic brain injury (TBI) and their relationship to patient pre-injury and injury characteristics. Design Prospective observational cohort. Setting multiple acute inpatient rehabilitation units or hospitals. Participants 2,130 individuals with TBI (complicated mild, moderate, or severe) admitted for inpatient rehabilitation. Interventions NA Main Outcome Measure(s) NA Results Most frequently administered was narcotic analgesics (72% of sample) followed by antidepressants (67%), anticonvulsants (47%), antianxiolytics (33%), hypnotics (30%), stimulants (28%), antipsychotics (25%), antiparkinson agents (25%), and miscellaneous psychotropics (18%). The psychotropic agents studied were administered to 95% of the sample with 8.5% receiving only 1 and 31.8% receiving 6 or more. Degree of psychotropic medication administration varied widely between sites. Univariate analyses indicated younger patients were more likely to receive anxiolytics, antidepressants, antiparkinson agents, stimulants, antipsychotics, and narcotic analgesics, while those older were more likely to receive anticonvulsants and miscellaneous psychotropics. Men were more likely to receive antipsychotics. All medication classes were less likely administered to Asians, and more likely to those with more severe functional impairment. Use of anticonvulsants was associated with having seizures at some point during acute care or rehabilitation stays. Narcotic analgesics were more likely for those with history of drug abuse, history of anxiety and depression (premorbid or during acute care), and severe pain during rehabilitation. Psychotropic medication administration increased rather than decreased during the course of inpatient rehabilitation in each of the medication categories except for narcotics. This observation was also true for medication administration within admission functional levels (defined

Role of serotonin in pathogenesis of analgesic induced headache

Energy Technology Data Exchange (ETDEWEB)

Srikiatkhachorn, A.

1999-12-16

Analgesic abuse has recently been recognized as a cause of deterioration in primary headache patients. Although the pathogenesis of this headache transformation is still obscure, and alteration of central pain control system is one possible mechanism. A number of recent studies indicated that simple analgesics exert their effect by modulating the endogenous pain control system rather than the effect at the peripheral tissue, as previously suggested. Serotonin (5-hydroxytryptamine ; 5-HT) has long been known to play a pivotal role in the pain modulatory system in the brainstem. In the present study, we investigated the changes in 5-HT system in platelets and brain tissue. A significant decrease in platelet 5-HT concentration (221.8{+-}30.7, 445.3{+-}37.4 and 467.2{+-}38.5 ng/10{sup 9} platelets, for patients with analgesic-induced headache and migraine patients, respectively, p<0.02) were evident in patients with analgesic induced headache. Chronic paracetamol administration induced a decrease in 5-HT{sub 2} serotonin receptor in cortical and brain stem tissue in experimental animals (B{sub max}=0.93{+-}0.04 and 1.79{+-}0.61 pmol/mg protein for paracetamol treated rat and controls, respectively, p<0.05). Our preliminary results suggested that chronic administration of analgesics interferes with central and peripheral 5-HT system and therefore possibly alters the 5-HT dependent antinociceptive system.

Post-marketing surveillance studies can provide supplemental data on the safety of medications in the general population. This study aimed to evaluate the safety of analgesic regimens including the NSAID lornoxicam in the short-term treatment of postoperative pain in a clinically relevant population. Randomized, open-label, multicentre, multinational, observational cohort study of 4 days' duration. In-hospital postoperative setting, with discharge to home treatment within 24 hours of surgery. Adults aged > or =18 years expected to be in need of analgesic treatment after day-case surgery. Analgesic regimens containing lornoxicam were compared with a standard analgesic treatment, which was defined as the treatment that the patient would normally receive at the centre. Following day-case surgery, patients were provided with appropriate analgesic medication, and adverse events (AEs; defined as all recorded events with symptoms) were recorded by the investigator during the in-hospital stay and by the patient for the next 3 days using entries recorded morning and evening in a patient diary. Statistical analyses tested for between-treatment differences in AEs, adverse drug reactions (ADRs; defined as events probably, possibly or unlikely to be related to treatment) and gastrointestinal AEs (GI-AEs). A total of 4152 patients were randomized to treatment. Since 400 patients did not take any analgesic, the safety population consisted of 1838 patients for lornoxicam and 1914 patients for standard analgesic treatment. Demographic and disease characteristics were similar between the two treatment groups, as were the type of surgery and the anaesthesia used in surgery. In the safety population, 16.9% of patients received no analgesic in hospital, and when analgesics were provided they were often administered in combination. Similarly, approximately 17% of patients did not take any analgesics at home. AEs were reported in 27.1% and 29.4% of patients in the lornoxicam and standard

Full Text Available Abstract Background and objective: NAS is a combination of signs and symptoms that due to physical and mental dependency, develops in neonates born from drug addicted mothers. The onset of NAS varies in accordance with the type, amount, frequency and duration of substance used. Because of diverse and unclear pattern of substance abuse in Iranian addicted pregnant mothers in comparison with western countries, this multi-center study has been designed to evaluate NAS in neonates born from drug addicted mothers. Material and method: A cross sectional study was carried out on newborns of narcotic addicted mothers during the first six months of 2008. The newborn’s status and clinical signs were checked by physical examination and scored by the Finnegan scoring system. Results: In this study 100 neonates born from narcotic addicted mothers were examined; the most used narcotic was crack (36%. 60% of neonates showed signs of NAS. The most prevalent signs of NAS were increased muscle tonicity (60%/7, irritability (59%/6 and increased moro reflex (51%/8. Neonates born from crack abusers, in comparison with other drugs, were significantly at risk of NAS (100% vs.87%, p

On the basis of analysis of 1,879 samples of narcotics confiscated in Jutland and Funen during the period 1981-1988, the individual types of drugs are described as regards occurrence and quality. Cannabis and heroin were found in the illegal market during the entire period. Amphetamine was rarely observed prior to 1985 but comprised half of the illegal drugs examined in 1988. Cocaine was encountered in only 1% of the samples. Designer drugs were not seen. Heroin occurred relatively most frequently in Aarhus, Odense and Esbjerg while amphetamine and cannabis were found in all parts of Jutland and Funen. The samples of heroin and amphetamine varied greatly as regards strength and the types and quantities of cutting agents. The majority of the samples were adulterated and/or diluted with substances such as caffeine and phenazone and the sugars, glucose and lactose.

The behavioral response to pain is driven by sensory and affective components, each of which is mediated by the CNS. Subjective pain ratings are used as readouts when appraising potential analgesics; however, pain ratings alone cannot enable a characterization of CNS pain circuitry during pain processing or how this circuitry is modulated pharmacologically. Having a more objective readout of potential analgesic effects may allow improved understanding and detection of pharmacological efficacy for pain. The pharmacological/functional magnetic resonance imaging (phMRI/fMRI) methodology can be used to objectively evaluate drug action on the CNS. In this context, we aimed to evaluate two drugs that had been developed as analgesics: one that is efficacious for pain (buprenorphine (BUP)) and one that failed as an analgesic in clinical trials aprepitant (APREP). Using phMRI, we observed that activation induced solely by BUP was present in regions with μ-opioid receptors, whereas APREP-induced activation was seen in regions expressing NK(1) receptors. However, significant pharmacological modulation of functional connectivity in pain-processing pathways was only observed following BUP administration. By implementing an evoked pain fMRI paradigm, these drugs could also be differentiated by comparing the respective fMRI signals in CNS circuits mediating sensory and affective components of pain. We report a correlation of functional connectivity and evoked pain fMRI measures with pain ratings as well as peak drug concentration. This investigation demonstrates how CNS-acting drugs can be compared, and how the phMRI/fMRI methodology may be used with conventional measures to better evaluate candidate analgesics in small subject cohorts.

Full Text Available Background and Aims: Flupirtine maleate is a centrally acting, non-opioid analgesic with unique muscle relaxant properties as compared to common analgesics. The aim of this study was to compare post-operative analgesic efficacy of flupirtine maleate and ibuprofen in patients undergoing gynaecological ambulatory surgeries. Methods: This prospective, randomised controlled study was conducted in 60 women of American Society of Anesthesiologists physical status I/II, 18-70 years of age and scheduled to undergo gynaecological ambulatory surgeries. The participants were randomised to receive either 100 mg oral flupirtine maleate (group flupirtine, n = 30 or 800 mg oral ibuprofen (group ibuprofen, n = 30, 1 h prior to surgery and then every 8 h for 48 h. Verbal Numerical Rating Scale (VNRS on movement was assessed at 0, 2, 4, 6 and 8 h following surgery. Following discharge from hospital, the patients were interviewed telephonically at 12, 24 and 48 h post-operatively. VNRS was statistically analysed using Mann-Whitney test. Results: VNRS on movement was statistically reduced at 2 h after surgery (P = 0.04 in group flupirtine as compared to group ibuprofen. The analgesic efficacy was similar in both the groups at 4, 6, 8, 12, 24 and 48 h after surgery. The satisfaction scores at 24 and 48 h post-operatively were superior in group flupirtine as compared to group ibuprofen (P < 0.001. Conclusion: Analgesic efficacy of flupirtine maleate was comparable with ibuprofen in patients in ambulatory gynaecological patients up to 48 h postoperatively with superior satisfaction scores.

Background The increased consumption of analgesics has been documented worldwide during the last 2 decades. The aim of the study was to examine the trends in opioid and nonopioid analgesic consumption in Croatia between 2007 and 2013. Methods Data on opioid consumption were extracted from the database of the national authority. All opioid and nonopioid analgesics were included in the analysis. Data were presented as defined daily doses per 1,000 inhabitants per day. Adequacy of opioid consumption was calculated using adequacy of consumption measure. Results During the examined 7-year period, the total consumption and total cost of all analgesics in Croatia showed continuous increase. In the M01A group (anti-inflammatory and antirheumatic products, nonsteroids), ibuprofen had an exponential increasing trend, and in 2011, it overtook diclofenac consumption. Ibuprofen and diclofenac had the highest consumption also in the M02A group of topical products for joint and muscular pain. Tramadol was by far the most consumed type of opioids (N02A group) and paracetamol in the group of other analgesics and antipyretics (N02B). The adequacy of consumption measure value was 0.19, indicating that Croatia is a country with a low opioid consumption. Conclusion Between 2007 and 2013, both consumption of analgesics and their cost in Croatia had an increasing trend. Comparisons with data from other countries, based on the published literature, indicate that analgesic consumption in Croatia is still relatively low. Calculation of the adequacy of opioid consumption indicated that Croatia is a country with low opioid consumption. Further studies are necessary for establishing whether current analgesic consumption in Croatia corresponds to patient needs. PMID:26357478

Morphine, a potent narcotic analgesic used for the treatment of acute and chronic pain, was chemically incorporated into a poly(anhydride-ester) backbone. The polymer termed "PolyMorphine", was designed to degrade hydrolytically releasing morphine in a controlled manner to ultimately provide analgesia for an extended time period. PolyMorphine was synthesized via melt-condensation polymerization and its structure was characterized using proton and carbon nuclear magnetic resonance spectroscopies, and infrared spectroscopy. The weight-average molecular weight and the thermal properties were determined. The hydrolytic degradation pathway of the polymer was determined by in vitro studies, showing that free morphine is released. In vitro cytocompatibility studies demonstrated that PolyMorphine is non-cytotoxic towards fibroblasts. In vivo studies using mice showed that PolyMorphine provides analgesia for 3 days, 20 times the analgesic window of free morphine. The animals retained full responsiveness to morphine after being subjected to an acute morphine challenge. Copyright © 2012 Elsevier B.V. All rights reserved.

This report describes the collaboration between the South Texas Specialized Crimes and Narcotics Task Force (STSCNTF) and Sandia National Laboratories (SNL) in a field test that provided prototype hand-held trace detection technology for use in counter-drug operations. The National Institute of Justice (NIJ)/National Law Enforcement and Corrections Technology Center (NLECTC)/Border Research and Technology Center (BRTC) was contacted by STSCNTF for assistance in obtaining cutting-edge technology. The BRTC created a pilot project for Sandia National Laboratories (SNL) and the STSCNTF for the use of SNL’s Hound, a hand-held sample collection and preconcentration system that, when combined with a commercial chemical detector, can be used for the trace detection of illicit drugs and explosives. The STSCNTF operates in an area of high narcotics trafficking where methods of concealment make the detection of narcotics challenging. Sandia National Laboratories’ (SNL) Contraband Detection Department personnel provided the Hound system hardware and operational training. The Hound system combines the GE VaporTracer2, a hand-held commercial chemical detector, with an SNL-developed sample collection and preconcentration system. The South Texas Task force reported a variety of successes, including identification of a major shipment of methamphetamines, the discovery of hidden compartments in vehicles that contained illegal drugs and currency used in drug deals, and the identification of a suspect in a nightclub shooting. The main advantage of the hand-held trace detection unit is its ability to quickly identify the type of chemical (drugs or explosives) without a long lag time for laboratory analysis, which is the most common analysis method for current law enforcement procedures.

Validated data regarding HIV-transmission in prisons in developing countries is scarce. We examined sexual and injecting drug use behavior and HIV and HCV transmission in an Indonesian narcotic prison during the implementation of an HIV prevention and treatment program during 2004-2007 when the Banceuy Narcotic Prison in Indonesia conducted an HIV transmission prevention program to provide 1) HIV education, 2) voluntary HIV testing and counseling, 3) condom supply, 4) prevention of rape and sexual violence, 5) antiretroviral treatment for HIV-positive prisoners and 6) methadone maintenance treatment. During a first survey that was conducted between 2007 and 2009, new prisoners entered Banceuy Narcotics Prison were voluntary tested for HIV and HCV-infection after written informed consent was obtained. Information regarding sexual and injecting risk behavior and physical status were also recorded at admission to the prison. Participants who tested negative for both HIV and HCV during the first survey were included in a second survey conducted during 2008-2011. During both surveys, data on mortality among HIV-seropositive patients were also recorded. All HIV-seropositive participants receive treatment for HIV. HIV/ AIDS-related deaths decreased: 43% in 2006, 18% in 2007, 9% in 2008 and 0% in 2009. No HIV and HCV seroconversion inside Banceuy Narcotic Prison were found after a median of 23 months imprisonment (maximum follow-up: 38 months). Total of 484.8 person-years observation was done. Participants reported HIV transmission risk-behavior in Banceuy Prison during the second survey was low. After implementation of HIV prevention and treatment program, no new HIV or HCV cases were detected and HIV-related mortality decreased.

Transmitter peptides having immunostimulant and endorphine-like properties were isolated from supernatant of medullary cell culture. Bioregulatory peptides were called myelopeptides. Myelopeptides provoked changes of the summation-threshold index in rats, which augmented in time. These changes pointed to the realization of the analgetic effect of myelopeptides via the spinal-stem structures of the central nervous system. Having a remarkable analgesic effect myelopeptides administered in the doses tested did not produce any action on the behavioral responses. The latter circumstance makes them differ from narcotic analgesics and known endorphines.

Analgesic effects of branding in treatment of headaches.

Science.gov (United States)

Branthwaite, A; Cooper, P

1981-01-01

The effect of branding--that is, the labelling and marketing--of a well-known proprietary analgesic used to treat headaches was studied in a sample of women given a branded or unbranded form with either an inert or an active formulation. The sample was also divided according to whether the subjects were regular users of the brand or users of other brands. The findings showed that branded tablets were overall significantly more effective than unbranded tablets in relieving headaches. Differential effects were observed: the effects of branding were more noticeable one hour after the tablets were taken compared with 30 minutes; in the women given the placebo; and in the users of the brand compared with the users of other brands. It is hypothesised that these effects are due to increased confidence in obtaining relief with a well-known brand, and that branding has an analgesic effect that interacts with the analgesic effects of placebos and active ingredients.

Full Text Available Background/Aim. Ropivacaine is a relatively new longacting local anesthetic. The aim of this study was to compare the postoperative analgesic effect of topical anesthetics ropivacaine 0.75% and lidocaine 2% with adrenaline in the postoperative treatment of periapical lesions in the maxilla. Methods. The study was conducted on 60 subjects, divided into two groups. The study-group received 0.75% ropivacaine without a vasoconstrictor, while the control group was treated with 2% lidocaine with adrenaline (1 : 80.000. Block anesthesia for n. infraorbitalis was used and local anesthetics were applied also on the palatine side for the end branches of n. nasopalatinus. The following parameters were observed: time elapsed from the application of an anesthetic until the first occurrence of pain after the surgery and first intake of an analgesic, the intensity of initial pain, pain intensity 6 h after the application of anesthetics and the total number of analgesics taken within 24 h after the completion of surgery. Results. The pain appeared statistically significantly earlier in the patients who had been given lidocaine with adrenaline (p < 0.001, while statistically significantly higher mean values of initial postoperative pain (p < 0.05 and pain intensity 6 h after the intervention (p < 0.01 were also registered in the same group of patients. In the period of 24 h upon the intervention, the study-group patients were taking less analgesics as compared to the control-group subjects (46.6% vs 73.3%, who were given analgesics earlier, although no statistically significant differences were observed related to the number of analgesic doses taken. Conclusion. The results of our study indicate a better postoperative analgesic effect of ropivacaine as compared to lidocaine with adrenaline.

Pain affects between 40 and 85% of Parkinson's disease (PD) patients. It is a frequently disabling and overlooked feature, which can significantly reduce health-related quality of life. Unfortunately, there are no universally recommended treatments for this condition. Evidence about the efficacy and safety of available analgesic treatments is summarized in this review. Potential targets for upcoming therapies are then discussed in light of what is currently known about the physiopathology of pain in PD. Protocols for efficacy and safety assessment of novel analgesic therapies are discussed. Finally, critical aspects of study protocol design such as patient selection or outcomes to be evaluated are discussed. Preliminary results indicate that duloxetine, cranial electrotherapy stimulation, rotigotine, subthalamic or pallidum nuclei stimulation or lesion or levodopa could be effective for treating pain in PD. Similarly, some case reports indicate that repetitive transcranial magnetic stimulation (rTMS) or apomorphine could be effective for relieving painful off-period dystonia. Clinical trials with rTMS or oxycodone/naloxone prolonged-release tablets for neuropathic pain or botulinum toxin for off-period dystonia are underway. Success of clinical trials about analgesic strategies in PD will depend on the selection of the right PD population to be treated, according to the type of pain, and the proper selection of study outcomes and follow-up of international recommendations.

The aim of this analysis is to evaluate the costs of 72-hour postoperative pain treatment in patients undergoing major abdominal, orthopedic and thoracic procedures in nine different Italian hospitals, defined as the cumulative cost of drugs, consumable materials and time required for anesthesiologists, surgeons and nurses to administer each analgesic technique. Nine Italian hospitals have been involved in this study through the administration of a questionnaire aimed to acquire information about the Italian clinical practice in terms of analgesia. This study uses activity-based costing (ABC) analysis to identify, measure and give value to the resources required to provide the therapeutic treatment used in Italy to manage the postoperative pain patients face after surgery. A deterministic sensitivity analysis (DSA) has been performed to identify the cost determinants mainly affecting the final cost of each treatment analyzed. Costs have been reclassified according to three surgical macro-areas (abdominal, orthopedic and thoracic) with the aim to recognize the cost associated not only to the analgesic technique adopted but also to the type of surgery the patient faced before undergoing the analgesic pathway. Fifteen different analgesic techniques have been identified for the treatment of moderate to severe pain in patients who underwent a major abdominal, orthopedic or thoracic surgery. The cheapest treatment actually employed is the oral administration "around the clock" (€ 8.23), whilst the most expensive is continuous peripheral nerve block (€ 223.46). The intravenous patient-controlled analgesia costs € 277.63. In terms of resources absorbed, the non-continuous administration via bolus is the gold standard in terms of cost-related to the drugs used (€ 1.28), and when administered pro re nata it also absorbs the lowest amount of consumables (€0.58€) compared to all other therapies requiring a delivery device.

This study investigates the importance of communication in surgery and how delivering preoperative patient education can lead to better health outcomes postoperatively, via promoting tolerable pain scores and minimizing the use of narcotics after surgery. Patients who underwent outpatient surgery were randomly divided into groups to compare the pain scores of those who received preoperative patient education, the experimental group, and those who did not receive any form of patient education, the control group. Two weeks before surgery, the experimental group subjects received oral and written forms of patient education consisting of how the body responds to pain, and how endorphins cause natural analgesia. Moreover, patients were educated on the negative effects narcotics have on endorphin production and activity, as well as mechanisms of non-opioid analgesics. Of the 69 patients in the experimental group, 90% declined a prescription for hydrocodone after receiving preoperative education two weeks prior to surgery. The control group consisted of 66 patients who did not receive preoperative patient education and 100% filled their hydrocodone prescriptions. Patients in both groups were offered and received gabapentin and celecoxib preoperatively for prophylaxis of postoperative pain unless they declined. The control groups were found to have average pain scores significantly greater (P groups and also a significantly longer (P communication, which can serve as an effective means to minimize narcotic analgesia after surgery.

To validate the traditional use of the crude drug through in vivo and in vitro evaluation of the anti-inflammatory, analgesic and antioxidant properties of its extracts. Sequential hexane, dichloromethane, methanol and total methanol extracts were studied using bioguided fractionation. The following activities were investigated: analgesic (writhing test), oral and topic anti-inflammatory (paw- and ear-induced edema), free radical scavenging and antioxidant activities (1,1-diphenyl-2-picrylhydrazyl, DPPH, superoxide anion, lipid peroxidation and xanthine oxidase inhibition). Sodium naproxen, nimesulide, indomethacin were used as reference drugs for in vivo, quercetin and allopurinol for in vitro assays. A mixture of alpha- and beta-amyrins was isolated from the hexane extract that showed 41.2% of analgesic effect at 600 mg/kg, inhibited by 47.7 and 79.0% the arachidonic acid (AA) and 12-deoxyphorbol-13-decanoate (TPA)-induced inflammation at 3mg/20 microL/ear, respectively. A mixture of beta-sitosterol, stigmasterol, stigmastenol, stigmastanol and campesterol was isolated from the fraction CD4-N and beta-sitosterol-glycoside from the fraction CD5-N, reducing TPA-induced inflammation by 78.2 and 83.7% at 1mg/20 microL/ear, respectively. The fraction CD4-N at 300 mg/kg also showed analgesic activity (38.7%). The methanol extract at 600mg/kg per os showed anti-inflammatory effect (61.4%), topic anti-inflammatory (56.7% on TPA) and analgesic activity (38.5%). Verbascoside and luteolin-7-O-glucoside were the major components of the methanol extract; apigenin 7-O-glucoside was also detected. Inhibition of superoxide anion, lipoperoxidation, and DPPH bleaching effect was found in the methanol serial and global extracts. The present report demonstrate the analgesic and anti-inflammatory properties of Buddleja globosa and validate its use in Chilean traditional medicine.

A variety of 4(1-pyrrolidinyl) piperidine analogs 2-6 with variable substituents on phenyl ring of phenacyl moiety were synthesized and evaluated for their analgesic inhibitory potential by tail flick method revealed significant analgesic activity. The synthetic compounds exhibit analgesic inhibitory potential was ranging from significant to highly significant activity. Compounds were evaluated by thermal stimuli (tail immersion method) at the dose of 50 mg/kg of body weight. The compounds 2-5 showed significant and highly significant analgesic activity. Pethidine was used as reference drug. Same compounds tested at the dose of 75mg/kg of body weight showed toxicity. The size of the substituent, electron donating or withdrawing affect of substituents as well as the position of substituent on phenyl ring affected the activity. These compounds could be considered to develop a new class of analgesics. (author)

Doan, Lisa; Choi, Daniel; Kline, Richard

2017-10-01

Pain is common in older adults but may be undertreated in part due to concerns about medication toxicity. Analgesics may affect cognition. In this retrospective cohort study, we used the Alzheimer's Disease Neuroimaging Initiative (ADNI) database to examine the interaction of cognitive status and medications, especially non-steroidal anti-inflammatory drugs (NSAIDs). We hypothesized NSAID use would be associated with cognition and that this could be mediated through changes in brain structure. In this post hoc analysis of the ADNI database, subjects were selected by searching the "concurrent medications log" for analgesic medications. Subjects were included if the analgesic was listed on the medication log prior to enrollment in ADNI and throughout the study. Subjects taking analgesics, particularly NSAIDs, at each study visit were compared to control subjects taking no analgesics. Using descriptive statistics as well as univariate, multivariate and repeated measure ANOVA, we explored the relationship between NSAID use and scores for executive function and memory related cognitive activities. We further took advantage of the extensive magnetic resonance imaging (MRI) data available in ADNI to test whether cognitive change was associated with brain structure. The multitude of imaging variables was compressed into a small number of features (five eigenvectors (EV)) using principal component analysis. There were 87 NSAID users, 373 controls, and 71 taking other analgesics. NSAID use was associated with higher executive function scores for cognitively normal (NL) subjects as well as subjects with mild cognitive impairment (MCI). NSAID use was also associated with higher memory scores, but for NL females only. We analysed MRI data using principal component analysis to generate a set of five EVs. Examining NL and MCI subjects, one EV had significantly larger values in subjects taking NSAIDs versus control. This EV was one of two EVs which significantly correlated with

Piracetam is a prototype of nootropic drugs used to improve cognitive impairment. However, recent studies suggest that piracetam can have analgesic and anti-inflammatory effects. Inflammatory pain is the result of a process that depends on neutrophil migration, cytokines and prostanoids release and oxidative stress. We analyze whether piracetam has anti-nociceptive effects and its mechanisms. Per oral pretreatment with piracetam reduced in a dose-dependent manner the overt pain-like behavior induced by acetic acid, phenyl-p-benzoquinone, formalin and complete Freund's adjuvant. Piracetam also diminished carrageenin-induced mechanical and thermal hyperalgesia, myeloperoxidase activity, and TNF-α-induced mechanical hyperalgesia. Piracetam presented analgesic effects as post-treatment and local paw treatment. The analgesic mechanisms of piracetam were related to inhibition of carrageenin- and TNF-α-induced production of IL-1β as well as prevention of carrageenin-induced decrease of reduced glutathione, ferric reducing ability and free radical scavenging ability in the paw. These results demonstrate that piracetam presents analgesic activity upon a variety of inflammatory stimuli by a mechanism dependent on inhibition of cytokine production and oxidative stress. Considering its safety and clinical use for cognitive function, it is possible that piracetam represents a novel perspective of analgesic. Copyright © 2013 Elsevier Inc. All rights reserved.

The aim of this survey was to evaluate the current practice regarding pain assessment and pain management strategies adopted in commonly performed minor painful procedures in Northern Italian Neonatal Intensive Care Units (NICUs). A multicenter survey was conducted between 2008 and 2009 in 35 NICUs. The first part of the survey form covered pain assessment tools, the timing of analgesics, and the availability of written guidelines. A second section evaluated the analgesic strategies adopted in commonly performed painful procedures. The listed analgesic procedures were as follows: oral sweet solutions alone, non-nutritive sucking (NNS) alone, a combination of sweet solutions and NNS, breast-feeding where available, and topical anesthetics. Completed questionnaires were returned from 30 neonatal units (85.7% response rate). Ten of the 30 NICUs reported using pain assessment tools for minor invasive procedures. Neonatal Infant Pain Scale was the most frequently used pain scale (60%). Twenty neonatal units had written guidelines directing pain management practices. The most frequently used procedures were pacifiers alone (69%), followed by sweet-tasting solutions (58%). A 5% glucose solution was the most frequently utilized sweet-tasting solution (76.7%). A minority of NICUs (16.7%) administered 12% sucrose solutions for analgesia and the application of topical anesthetics was found in 27% of NICUs while breast-feeding was performed in 7% of NICUs. This study found a low adherence to national and international guidelines for analgesia in minor procedures: the underuse of neonatal pain scales (33%), sucrose solution administration before heel lance (23.3%), topical anesthetics before venipuncture, or other analgesic techniques. The presence of written pain control guidelines in these regions of Northern Italy increased in recent years (from 25% to 66%). © 2010 World Institute of Pain.

Sida tiagii Bhandari mostly found in India and Pakistan which belongs to family Malvaceae, is traditionally used as analgesic, anti-inflammatory, sedative, anxiolytic, anti-seizure and anti-platelet. The present study was done to explore the analgesic activity of various extracts of fruits of the plant Sida tiagii Bhandari. The grinded fruits were extracted with 90% ethanol and partitioned with n-hexane (n-hexane extract; HS) and ethyl acetate (ethyl acetate extract; EAS), successively. The residual ethanol fraction (residual ethanol extract; RES) was also prepared by drying on water bath separately. All three extracts were administered orally at a dose of 200 mg/kg and 500 mg/kg of body weight. The analgesic activity of above extracts was evaluated by using acetic acid induced writhing, tail immersion and tail flick tests in Swiss albino mice. The EAS extract was found to reduce pain and RES extract of Sida tiagii B. was found to have good analgesic activity in comparison to other extracts.

Intahphuak, S; Khonsung, P; Panthong, A

2010-02-01

This study investigated some pharmacological properties of virgin coconut oil (VCO), the natural pure oil from coconut [Cocos nucifera Linn (Palmae)] milk, which was prepared without using chemical or high-heat treatment. The anti-inflammatory, analgesic, and antipyretic effects of VCO were assessed. In acute inflammatory models, VCO showed moderate anti-inflammatory effects on ethyl phenylpropiolate-induced ear edema in rats, and carrageenin- and arachidonic acid-induced paw edema. VCO exhibited an inhibitory effect on chronic inflammation by reducing the transudative weight, granuloma formation, and serum alkaline phosphatase activity. VCO also showed a moderate analgesic effect on the acetic acid-induced writhing response as well as an antipyretic effect in yeast-induced hyperthermia. The results obtained suggest anti-inflammatory, analgesic, and antipyretic properties of VCO.

A short history of anti-rheumatic therapy - V. Analgesics

Directory of Open Access Journals (Sweden)

P. Marson

2011-06-01

Full Text Available The pharmacological treatment of pain has very ancient origins, when plant-derived products were used, including mandrake extracts and opium, a dried latex obtained from Papaver somniferum. In the XVI and XVII centuries opium came into the preparation of two compounds widely used for pain relief: laudanum and Dover’s powder. The analgesic properties of extracts of willow bark were then recognized and later, in the second half of the XIX century, experimental studies on chemically synthesized analgesics were planned, thus promoting the marketing of some derivatives of para-amino-phenol and pyrazole, the predecessors of paracetamol and metamizol. In the XX century, nonsteroidal anti-inflammatory drugs were synthesized, such as phenylbutazone, which was initially considered primarily a pain medication. The introduction on the market of centrally acting analgesics, such as tramadol, sometimes used in the treatment of rheumatic pain. is quite recent.

Anecdotal evidence suggests that many veterinarians may not use analgesics in livestock for routine surgical procedures or painful disease states. To investigate this, we conducted a national mail survey of a random sample of 1431 Canadian veterinarians (response rate, 50.1%). Questions primarily concerned veterinarians’ analgesic usage for common surgeries and medical conditions in beef and dairy cattle, pigs, and horses, and attitudes toward pain management. More than 90% of veterinarians used analgesic drugs for equine surgeries, for cesarean section in sows and cows, and for bovine claw amputation and omentopexy. However, in these and other categories, the analgesics used were often inadequate, and many veterinarians did not give analgesics to young animals. When castrated, 6 mo of age, and 95.8% of horses. Respondents largely agreed that there are no long-acting, cost-effective analgesics available for use in livestock (median rating 8/10; interquartile range 4–9), and that the long or unknown withdrawal periods of some drugs outweighed the benefits of using them (median rating 7/10; interquartile range 4–9). The results indicate an urgent need for veterinarians to manage pain in livestock better. Continuing education would help, as would an increase in the number of approved, cost-effective analgesic drugs with known withdrawal periods. PMID:17334029

de Kauwe, Tyron; Kimble, Benjamin; Govendir, Merran

2014-06-01

Recent publications report that some therapeutic drugs used in koalas (Phascolarctos cinereus) have poor oral absorption and are rapidly eliminated. Therefore, information on both the analgesic drug dosage regimens used to treat koalas in Australia and koala caretakers' perceptions of the efficacy of these drugs to control pain was collected for the purpose of identifying the most popular analgesics to prioritize future analgesic pharmacokinetic studies for this species. A one-page, double-sided questionnaire was distributed both electronically and by mail to Australian koala care facilities such as zoos and wildlife hospitals. Information was received from 13 respondents. Nonsteroidal anti-inflammatory drugs (NSAIDs) were the most frequently used analgesics, followed by full micro- and partial opioid receptor agonists and acetaminophen with or without codeine. The full micro-opioid receptor agonists and acetaminophen with or without codeine were most consistently considered efficacious, with wider variation in perceived efficacy of the NSAIDs. Analgesic drug combinations were generally thought efficacious.

Analgesics also known as painkillers are widely used for pain relief. There are severe health implications associated with excessive use of analgesics. This paper examines factors influencing the use of analgesics among construction workers in the Ga-East Municipality (GEM) of the Greater Accra region of Ghana. This is a cross-sectional study involving 206 construction workers randomly sampled from 7 construction sites in the GEM. A structured questionnaire was used to elicit responses on knowledge of analgesics, types of analgesics used and factors influencing the use of analgesics. Chi-square test analysis was used to examine factors influencing analgesic use. The majority of workers were aged between 15 to 44 years (89.8%) and 51.9 percent of respondents had completed Junior high school. Many respondents (68.0%) used Brand 1 a locally manufactured analgesic with paracetamol, aspirin and caffeine as the active ingredients and 31.6 percent of respondents had no knowledge of possible side effects of continuous use of analgesics. Chi square analysis showed that age was significantly associated with use of analgesics (peffects did not influence use (p>0.05). Television and radio advertisements influenced use of analgesics (peffects was inadequate. Pharmacists and chemists involvement in education of clients of the side effects of analgesics is highly recommended to minimise misuse. The Food and Drugs Authority should regulate the proliferation of advertisements for analgesics in the media. None declared.

Crisp, Catrina C; Khan, Madiha; Lambers, Donna L; Westermann, Lauren B; Mazloomdoost, Donna M; Yeung, Jennifer J; Kleeman, Steven D; Pauls, Rachel N

This study aimed to determine the effect of intravenous acetaminophen versus placebo on postoperative pain, satisfaction with pain control, and narcotic use after vaginal reconstructive surgery. This was an institutional review board-approved, double-blind placebo-controlled randomized trial. Women scheduled for reconstructive surgery including vaginal hysterectomy and vaginal vault suspension were enrolled. Subjects received 1000 mg of intravenous acetaminophen or 100 mL placebo every 6 hours for 24 hours. Pain and satisfaction with pain control were assessed using visual analog scales and a numeric rating scale. Visual analog scales were collected at 18 and 24 hours postoperatively and at discharge. A sample size calculation determined 90 subjects would be required to detect a 30% reduction in postoperative narcotic use with 80% power and significance level of 0.05. One hundred subjects were enrolled. There were no differences in demographics or surgical data and no difference in narcotic consumption at multiple evaluation points. At 18 hours postoperative, median pain scores at rest were 27.0 (interquartile range, 35.0) for acetaminophen and 35.0 (interquartile range, 44.5) for placebo, finding no difference (P = 0.465). Furthermore, pain with activity and numeric rating scale-assessed pain scales were similar (P = 0.328; P = 0.597). Although satisfaction with pain control was high overall (91.5), no difference was noted. Patients undergoing vaginal reconstructive surgery receiving perioperative intravenous acetaminophen did not experience a decrease in narcotic requirements or postoperative pain when compared with placebo. Reassuringly, pain scores were low and satisfaction with pain control was high for all subjects. The general use of this medication is not supported in these surgical patients.

Bottlenecks in the development of topical analgesics: molecule, formulation, dose-finding, and phase III design

Full Text Available Jan M Keppel Hesselink,1 David J Kopsky,2 Stephen M Stahl3 1Institute Neuropathic Pain, Bosch en Duin, the Netherlands; 2Institute Neuropathic Pain, Amsterdam, the Netherlands; 3University of California San Diego, La Jolla, CA, USA Abstract: Topical analgesics can be defined as topical formulations containing analgesics or co-analgesics. Since 2000, interest in such formulations has been on the rise. There are, however, four critical issues in the research and development phases of topical analgesics: 1 The selection of the active pharmaceutical ingredient. Analgesics and co-analgesics differ greatly in their mechanism of action, and it is required to find the most optimal fit between such mechanisms of action and the pathogenesis of the targeted (neuropathic pain. 2 Issues concerning the optimized formulation. For relevant clinical efficacy, specific characteristics for the selected vehicle (eg, cream base or gel base are required, depending on the physicochemical characteristics of the active pharmaceutical ingredient(s to be delivered. 3 Well-designed phase II dose-finding studies are required, and, unfortunately, such trials are missing. In fact, we will demonstrate that underdosing is one of the major hurdles to detect meaningful and statistically relevant clinical effects of topical analgesics. 4 Selection of clinical end points and innovatively designed phase III trials. End point selection can make or break a trial. For instance, to include numbness together with tingling as a composite end point for neuropathic pain seems stretching the therapeutic impact of an analgesic too far. Given the fast onset of action of topical analgesics (usually within 30 minutes, enrichment designs might enhance the chances for success, as the placebo response might decrease. Topical analgesics may become promising inroads for the treatment of neuropathic pain, once sufficient attention is given to these four key aspects. Keywords: topical, analgesics

Nonprescription analgesics and their use in solid-organ transplantation: a review.

Science.gov (United States)

Gabardi, Steven; Luu, Linh

2004-09-01

To review the pharmacology, adverse events, drug interactions, and use of the nonprescription analgesics in solid-organ transplant recipients. Studies evaluating nonprescription analgesics in solid-organ transplantation were considered for evaluation. English-language studies were selected for inclusion. Nonprescription analgesics (aspirin, choline salicylate, magnesium salicylate, sodium salicylate, ibuprofen, ketoprofen, naproxen sodium, and acetaminophen) are the most commonly purchased over-the-counter agents in the United States. These agents, although generally considered safe, have been associated with a number of toxicities. The salicylates and nonsteroidal anti-inflammatory drugs have been associated with gastrointestinal damage, hematologic changes, liver and kidney dysfunction, and breathing difficulties. Acetaminophen has been shown to induce hematologic changes and liver and renal dysfunction. A closer look at the nonprescription analgesics reveals their potential for harm when used by solid-organ transplant recipients. In this patient population, the salicylates and nonsteroidal anti-inflammatory drugs should generally be avoided if possible, because of their potential toxicities, especially renal dysfunction. Low-dose aspirin, for the prevention of cardiovascular and cardiocerebral events, appears to be safe, but patients must still be followed closely. Acetaminophen is generally considered the nonprescription analgesic and antipyretic of choice in transplant recipients because of its favorable toxicity profile. However, it is imperative that patients and transplant practitioners are aware that this agent is not without toxicities and proper monitoring is advised.

Applications of Monte Carlo technique in the detection of explosives, narcotics and fissile material using neutron sources

2009-01-01

The problem of illicit trafficking of explosives, narcotics or fissile materials represents a real challenge to civil security. Neutron based detection systems are being actively explored worldwide as a confirmatory tool for applications in the detection of explosives either hidden inside a vehicle or a cargo container or buried inside soil. The development of a system and its experimental testing is a tedious process and to develop such a system each experimental condition needs to be theoretically simulated. Monte Carlo based methods are used to find an optimized design for such detection system. In order to design such systems, it is necessary to optimize source and detector system for each specific application. The present paper deals with such optimization studies using Monte Carlo technique for tagged neutron based system for explosives and narcotics detection hidden in a cargo and landmine detection using backscatter neutrons. We will also discuss some simulation studies on detection of fissile material and photo-neutron source design for applications on cargo scanning. (author)

Low back pain syndromes most often occur due to overloading of the musculoskeletal system. The cause is a frequent, improper lifting of heavy objects, most commonly by those working physically, with repetitive movements of bending and straightening of the trunk (turning and bending with load). This problem affects not only adults but also children and adolescents. There is a growing interest in new forms of analgesic therapy nowadays, especially in those that exhibit synergistic therapeutic effects. The aim of this work is to evaluate the analgesic efficacy of magnetoledotherapy in patients with lumbar--sacrum spinal pain syndromes caused by joints degenerative changes. The examination was carried out in 66 patients of both sexes aged 30 to 76 (average 54.7 +/- 13.8) with low back pain syndrome caused by spinal degenerative changes. The patients were divided into three groups according to the applied analgesic therapy (magnetoledotherapy, magnetostimulation, TENS currents). Level of pain has been evaluated four times in all patients--before the start of therapy and after 5, 10 and 15 applications with the use of the modified Laitinen Questionnaire and Visual-Analoque Scale (VAS). Post therapy levels of pain in the studied patients decreased significantly. According to Laitinen questionnaire, the greatest improvement was observed in the group treated with magnetoledotherapy and TENS currents and the smallest improvement was observed in the group treated with magnetostimulation. 1. Magnetoledotherapy shows significant analgesic efficacy in patients with low back pain syndrome and shows no side effects. 2. Concurrent application of both the infrared radiation generated by LED's and magnetostimulation synergistically reinforces analgesic effect in patients with low back pain syndrome, especially in level of pain and frequency of its occurrence, which results in the increase of movement activity and decrease in administration of analgesics.

To describe the epidemiology of joint pains and document analgesics usage in an African context. Patients suffering from joint pain were recruited from nine sites located in Antananarivo, Madagascar, including 6 hospital services and 3 clinics. Doctors collected information on the etiology and characteristics of the patients' pain. Analgesics prescribed by these doctors were also documented. In total, 400 patients were enrolled in the study (52.5% women, mean age of 42.34 years ± 17.7 [4-86]). Pain of mechanical type was found in 260 participants, 65%; 95% CI [60.1% to 69.6%] and inflammatory type pains in 128 cases 32%; 95% CI [27.5% to 36.9%]. Mixed pains were found in 12 patients (3%). The median duration of pain prior to the consultation was 6.5 days. The average pain intensity was 57.9 ± 19.9 mm of a total of 100 mm maximum on a visual analogue scale, VAS. The etiologies of mechanical type pains were dominated by fracture, common low back pain and tendonitis. Arthrosis was the dominant cause of inflammatory type pain, followed by rheumatoid arthritis and gout. NSAIDs (74.5%) were the most frequently prescribed analgesics followed by paracetamol (49.5%), weak opioids (23%) and corticosteroids (12.25%). Two-thirds of medical prescriptions (65.3%) were of combined analgesics. These findings demonstrated that mechanical type pains were the main reason for consultations for joint pain in these situations in Antananarivo, Madagascar. The most frequently prescribed pain-relieving medications were NSAIDs, paracetamol, weak opioids and corticosteroids. This descriptive study may be a useful starting point for further epidemiological studies of pain in the African context.

Multimodal analgesic methods are preferred for the treatment of postoperative pain; as a result, the additive effects of analgesics are provided while probable side effects are avoided. The current study aimed to compare the effects of the combination of dexketoprofen and paracetamol with regard to postoperative pain therapy. Ninety-six patients who underwent non-malignant gynaecological laparotomy operations were included in this study. Patients were randomized into 3 groups. Group D received 50 mg intravenous dexketoprofen 15 minutes before the end of the operation and 8 and 16 hours after the operation. Group P received 1 g intravenous paracetamol and Group DP received the combination of 500 mg paracetamol and 25 mg dexketoprofen at the same time intervals. All patients received morphine infusion after operation. Total morphine consumption at 24 hours, visual analog scale, patient satisfaction and side effects were investigated. Comparison of the visual analog scale scores revealed that the Group DP presented lower scores at 24th hours compared to the other groups; and the difference between Group DP and Group D was statistically significant. Total morphine consumption was not significantly different between the three groups. The minimum number of side effects was observed in the Group DP. Co-administration of paracetamol, dexketoprofen and morphine provided good analgesia and fewer side effects in gynaecological abdominal surgery.

Full Text Available Background: The pattern of drug abuse in Iran has dramatically changed in recent years, turning from the traditional opioids [opium, opium dross, and refined opium dross (Shireh] into drugs with newer forms. The present study is aimed at investigating the frequency of pathological changes in the lungs of bodies with positive postmortem toxicology results for narcotics and psychotropic substances autopsied in the forensic dissection hall of Tehran, Iran [the Iranian Legal Medicine Organization (LMO]. Methods: The present study is a cross-sectional descriptive study. The sample consisted of 153 bodies, which had been referred to the LMO with positive results in postmortem toxicology for narcotics and psychotropic substances. Results: We found that narcotic drugs and psychotropic substances were used more in men than women. Moreover, the average age of death due to drug use was 36 years old. In addition, methamphetamine was the mostly-used type of substances, and smoking was the most widely used method to use the drugs. Besides, the dominant consistency and color of the lungs of half of the bodies investigated were elastic brown-gray. Moreover, the most common pathologic changes observed in the lungs of the bodies investigated were congestion and edema. Conclusion: Given the prevalence of pathological changes in the lungs of the examined bodies and congestion, edema, and pulmonary hemorrhage, the results of the present study can be particularly effective in determining the drug use and the resultant death in the absence of any previous records and/or a negative result of toxicology.

Post-Market Research Clinical evidence supports the use of dexketoprofen trometamol (DEX) to manage acute postoperative pain. However, controversies surround the impact of the use of this drug in preoperative analgesic protocols. The aim of the present meta-analysis was to evaluate the effectiveness of the preoperative administration of DEX under postoperative pain conditions. Electronic and manual searches were conducted through diverse electronic databases. A systematic review and meta-analysis to evaluate the analgesic efficacy of the preoperative administration of DEX was performed including Randomized Clinical Trials (RCTs) published between 2002 and 2017. Suitable individual studies were evaluated through a quality system, and the data were extracted and analyzed. Fourteen RTCs were included (12 parallel trials and 2 cross-over trials), published in the English and Turkish languages. Follow-up periods ranged from 4, 6, 8, 24, and 48 hr. All trials measured the outcome result as Acute Pain Level (APL) (VAS, NRS, VRS), time to requiring a second dose of DEX or analgesic emergency and consumption of opioids via patient-controlled analgesia. When the comparators were other drugs - paracetamol, Lornoxicam or placebo during the preoperative time, preoperative administration of DEX was superior. When the comparison comprised preoperative and postoperative DEX, both alternatives exhibited comparable analgesic effects. The analgesic efficacy of the preoperative administration of DEX when compared to placebo, lornoxicam, and paracetamol on postoperative pain was evident. Preoperative administration of DEX compared to its immediate postoperative administration showed a similar analgesic effect. © 2017 Wiley Periodicals, Inc.

[Pain patients in street traffic. Do analgesics impair driving safety?].

Science.gov (United States)

Sohn, W

2003-06-05

Analgesics--in particular when self-prescribed or taken over the long term--may have a negative effect on safety on the road. This applies not only to vehicle drivers, but also to cyclists and pedestrians. Psychotropic effects of analgesics of all three WHO categories play a major causal role. Impairments may take the form of sleepiness, impaired vision, giddiness, loss of muscular tone or cardiovascular reactions. On the other hand, untreated severe pain has a high risk potential, since it may reduce both cognitive and psychomotoric performance. During the stabilization phase or dose adjustment of opioids, the patient must cautioned not to drive, and particular care must be taken in patients on concomitant or long-term medication or drinking excessive alcohol. In the last resort, the prescription of an analgesic is an individual decision involving both physician and patient.

The aim of this study was to examine trends and associated factors in the prescription of opioid analgesics, nonopioid analgesics, opioid and nonopioid analgesic combinations, and no analgesics by emergency physicians for nontraumatic dental condition (NTDC)-related visits. Our secondary aim was to investigate whether race/ethnicity is a possible predictor of receiving a prescription for either type of medication for NTDC visits in emergency departments (EDs) after adjustment for potential covariates. We analyzed data from the National Hospital Ambulatory Medical Care Survey for 1997-2000 and 2003-2007, and used multinomial multivariate logistic regression to estimate the probability of receiving a prescription for opioid analgesics, nonopioid analgesics, or a combination of both, compared with receiving no analgesics for NTDC-related visits. During 1997-2000 and 2003-2007, prescription of opioid analgesics and combinations of opioid and nonopioid analgesics increased, and that of no analgesics decreased over time. The prescription rates for opioid analgesics, nonopioid analgesics, opioid and nonopioid analgesic combinations, and no analgesics for NTDC-related visits in EDs were 43 percent, 20 percent, 12 percent, and 25 percent, respectively. Majority of patients categorized as having severe pain received prescriptions for opioids for NTDC-related visits in EDs. After adjusting for covariates, patients with self-reported dental reasons for visit and severe pain had a significantly higher probability of receiving prescriptions for opioid analgesics and opioid and nonopioid analgesic combinations. Prescription of opioid analgesics increased over time. ED physicians were more likely to prescribe opioid analgesics and opioid and nonopioid analgesic combinations for NTDC-related visits with reported severe pain. © 2014 American Association of Public Health Dentistry.

Full Text Available Purpose: To identify patterns of analgesic prescription and to explore patient-reported pain intensity, sleep disturbance, and quality of life among cancer patients with pain in Southeast Asia (SEA. Methods: This cross-sectional observational study included 465 adult outpatients prescribed analgesics for cancer pain for 1 month or longer at 22 sites in Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. Data on analgesic prescription and cancer characteristics were extracted from medical records. Pain intensity, sleep disturbance, and quality of life measures were recorded via questionnaires. Results: Most patients (84.4% had stage III or IV cancer. A total of 419 patients (90.7% were prescribed opioids; of these, 42.2% received only weak opioids, whereas 57.8% received at least one strong opioid. The mean worst pain intensity during the past 24 hours was 4.76 (standard deviation [SD], 2.47 on a scale of 0 (no pain to 10 (worst possible pain; the mean current pain intensity was 4.10 (SD, 2.61. More than half of patients (54.8% reported sleep disturbance caused by pain in the past 7 days. The majority of patients reported problems with pain/discomfort (82.3%, usual activities (65.8%, mobility (58.2%, and anxiety/depression (56.3%. The median daily dose prescribed in oral morphine equivalents was 30 mg for both morphine and tramadol. Conclusion: Despite unrelieved pain, sleep disturbance, and issues with quality of life, a notable proportion of patients were prescribed only weak opioids, and opioid doses prescribed were generally low. Efforts focused on encouragement of prescriptions with analgesic strength and/or doses proportional to the pain management needs of patients are vital to improve the status of cancer pain management in the region.

Pyrexia, algesia and inflammation are associated with several pathological conditions. Synthetic drugs available for the treatment of these conditions cause multiple unwanted effects. Several studies are ongoing worldwide to find natural healing agents with better safety profile. The current study was thus aimed at evaluating antipyretic, analgesic and anti-inflammatory activities of the methanolic extract of whole plant of V. betonicifolia (VBME). VBME was employed to assess antipyretic activity in yeast induced hyperthermia. Analgesic profile was ascertained in acetic acid induced writhing, hot plat and tail immersion test. Nevertheless, the anti-inflammatory activity was tested in carrageenan induced paw edema and histamine induced inflammatory tests. BALB/c mice were used at test doses of 100, 200 and 300 mg/kg body weight intra peritoneally (i.p). In yeast induced pyrexia, VBME demonstrated dose dependently (78.23%) protection at 300 mg/kg, similar to standard drug, paracetamol (90%) at 150 mg/kg i.p. VBME showed a dose dependent analgesia in various pain models i.e. acetic acid, hot plat and tail immersion having 78.90%, 69.96% and 68.58% protection respectively at 300 mg/kg. However, the analgesic action of VBME was completely antagonized by the injection of naloxone like opiate antagonists. Similarly carrageenan and histamine induces inflammation was significantly antagonized by VBME, 66.30% and 60.80% respectively at 300 mg/kg. It is concluded that VBME has marked antipyretic, analgesic and anti-inflammatory activities in various animal models and this strongly supports the ethnopharmacological uses of Viola betonicifolia as antipyretic, analgesic and anti-inflammatory plant.

The rhizome of Curcuma amada has been used as a folk medicine for the treatment of rheumatic disorders in the northern part of Bangladesh and has also used for the treatment of inflammation and fever in the Ayurvedic and Unani systems of medicine. Aim of the study was to investigate the analgesic principle of the MeOH extract of the rhizome of Curcuma amada by an in vivo bioassay guided chromatographic separation and purification, and the structure elucidation of the purified compound by spectroscopic methods. Dried powder of Curcuma amada rhizomes was extracted with MeOH. The analgesic activity of the crude extract and its chromatographic fractions as well as the purified compound itself was evaluated by the acetic acid induced writhing method and the formalin induced licking test in Swiss albino mice. The MeOH extract was separated by chromatographic methods and the pure active compound was purified by crystallization in hexanes. The structure of the pure compound was then elucidated by spectroscopic methods. The MeOH extract of Curcuma amada exhibited 41.63% and 45.53% inhibitions in the acetic acid induced writhing method at doses of 200mg/kg and 400mg/kg, respectively. It also exerted 20.43% and 28.50% inhibitions in early phase at doses of 200mg/kg and 400mg/kg, respectively, and 30.41% and 42.95% inhibitions in late phase at doses of 200mg/kg and 400mg/kg, respectively in the formalin induced licking test. Vacuum Liquid Chromatography (VLC) of crude extract yielded five fractions and Fr. 1 was found to have the most potent analgesic activity with inhibitions of 36.96% in the acetic acid induced writhing method and 47.51% (early phase), 39.50% (late phase) in the formalin induced licking test at a dose of 200mg/kg. Column chromatography of Fr. 1 on silica gel generated seven fractions (SF. 1-SF. 7). SF. 2 showed the most potent activity with inhibition of 49.81% in the acetic acid induced writhing method at a dose of 100mg/kg. Crystallization of SF. 2 yielded

2015-08-01

Full Text Available Abstract Drug abuse has grown over the days with significant development. Narcotics crime actually not only brings individual actors but tends to be a criminal offense syndicate or covert organization over the worlds. In this case the syndicate allegedly not only brings perpetrators of adults but feared the actors who are categorized as a child in accordance with the applicable laws. On the other side children occupy a special place in the law. Basic philosophy of the treatment of juvenile delinquents is for the best interests of the child but the fact that peoples behavior lately is very alarming how society is so easy to judge people suspected as perpetrators of criminal acts. The objective of this research is to understand the essence of the ultimum remedium principle as the basis for criminal punishment in the Indonesian criminal system in order to understand how the crisis is influencing drug phenomenon and drugs users lives and the extent of their impact on the settlement of narcotics crime against children as an offender. The outcomes of the research indicate that the Law No. 11 of 2012 regarding the Criminal Justice System for Juvenile Delinquency Rules of the Supreme Court of the Republic of Indonesia No. 4 of 2014 on Guidelines for Diversion and Law No. 35 of 2009 regarding Narcotics Crime have been given the freedom and legitimacy to the judge to apply the principle of ultimum remedium in handling cases of children in conflict with the law. As it turns out in practice however the ultimum remedium principle is rarely applied and tends to be overlooked in the process of juvenile justice.

Objective To evaluate the effects of an ultrasound-guided transverse abdominis plane (US-TAP) block used for postoperative pain relief by comparing the efficacy of two different volumes/concentrations of the local anaesthetic bupivacaine in patients undergoing laparoscopic cholecystectomies. Methods This randomized study enrolled patients undergoing laparoscopic cholecystectomies. They were randomized to two groups: group A received a 20 ml US-TAP block (50 mg bupivacaine +10 ml saline solution) and group B received a 30 ml US-TAP block (50 mg bupivacaine + 20 ml saline solution). The intraoperative consumption of remifentanil, the requirement for postoperative rescue analgesics, patient satisfaction scores, postoperative complications, and postoperative pain as measured by a visual analogue scale at 20 min, 12 h, and 24 h were recorded. Results A total of 60 patients enrolled in the study. There were no differences between the two groups with respect to demographic characteristics, duration of anaesthesia and patient satisfaction scores. The intraoperative consumption of remifentanil, postoperative VAS scores (20 min, 12 h and 24 h) and the requirement for postoperative analgesics were all significantly lower in group B who received a larger volume but a lower concentration of local anaesthetic solution compared with group A. Conclusion A US-TAP block can form part of a balanced postoperative analgesic regimen following laparoscopic cholecystectomy.

Full Text Available Opuntia dillenii (Nagphana traditionally used against inflammation and also possess analgesic effect. Thus in the present study analgesic properties of O. dillenii cladode methanol extract, its fractions obtained via vacuum liquid chromatography along with isolated α-pyrones, opuntiol and its glucoside, opuntioside were analyzed. The acetic acid-induced writhes were reduced by O. dillenii test agents with opuntioside being most effective (IC 50 26 ± 0.9 mg/kg and equipotent to diclofenac and β-sitosterol. Consistently, it also elicited most potent effect (IC 50: 28 ± 1.1 and 24 ± 1.2 mg/kg during early and late phases of formalin-induced paw licking, producing effect similar to diclofenac and indomethacin. It was also most effective in hot plate test. Naloxone (opioid antagonist reversed the analgesic effects of extract and fractions but failed to antagonize the opuntiol and opuntioside analgesic effects. In conclusion, edible O. dillenii extract, its fractions, opuntiol and opuntioside reduced peripheral and centrally mediated pain via opioid dependent and independent systems. Among them opuntioside emerged as most effective analgesic possibly due to the presence of glucose moiety at position 7 of its α-pyrone ring. This is the first report of opuntiol and opuntioside analgesic effect which may serve as lead compounds in designing of new analgesics.

Full Text Available Chemotherapy-induced intestinal mucositis is characterized by pain and a pro-inflammatory tissue response. Rat models are frequently used in mucositis disease investigations yet little is known about the presence of pain in these animals, the ability of analgesics to ameliorate the condition, or the effect that analgesic administration may have on study outcomes. This study investigated different classes of analgesics with the aim of determining their analgesic effects and impact on research outcomes of interest in a rat model of mucositis. Female DA rats were allocated to 8 groups to include saline and chemotherapy controls (n = 8. Analgesics included opioid derivatives (buprenorphine; 0.05mg/kg and tramadol 12.5mg/kg and NSAID (carprofen; 15mg/kg in combination with either saline or 5-Fluorouracil (5-FU; 150mg/kg. Research outcome measures included daily clinical parameters, pain score and gut histology. Myeloperoxidase assay was performed to determine gut inflammation. At the dosages employed, all agents had an analgesic effect based on behavioural pain scores. Jejunal myeloperoxidase activity was significantly reduced by buprenorphine and tramadol in comparison to 5-FU control animals (53%, p = 0.0004 and 58%, p = 0.0001. Carprofen had no ameliorating effect on myeloperoxidase levels. None of the agents reduced the histological damage caused by 5-FU administration although tramadol tended to increase villus length even when administered to healthy animals. These data provide evidence that carprofen offers potential as an analgesic in this animal model due to its pain-relieving efficacy and minimal effect on measured parameters. This study also supports further investigation into the mechanism and utility of opioid agents in the treatment of chemotherapy-induced mucositis.

1987-01-01

The effect of whole body irradiation of male mice with single doses of 3 and 7 Gy ( 60 Co source) on analgesic action of three morphine-like drugs was studied. Over the first 6 days after irradiation, the analgesic effect of alfentanil and fentanyl was significantly less pronounced in irradiated animals than in control ones. During the subsequent period of 24 days till the end of experiment, the analgesic effect in irradiated animals gradually increased reaching and exceeding the control values. On the contrary, the analgesic effect of butorphanole was less pronounced in irradiated animals than in control ones, although the difference was not significantly. The difference between butorphanole and other two drugs are probably due to chemical structure and the metabolic fate in the body. (author) 8 refs.; 2 figs

Full Text Available Abstract Background Pyrexia, algesia and inflammation are associated with several pathological conditions. Synthetic drugs available for the treatment of these conditions cause multiple unwanted effects. Several studies are ongoing worldwide to find natural healing agents with better safety profile. The current study was thus aimed at evaluating antipyretic, analgesic and anti-inflammatory activities of the methanolic extract of whole plant of V. betonicifolia (VBME. Methods VBME was employed to assess antipyretic activity in yeast induced hyperthermia. Analgesic profile was ascertained in acetic acid induced writhing, hot plat and tail immersion test. Nevertheless, the anti-inflammatory activity was tested in carrageenan induced paw edema and histamine induced inflammatory tests. BALB/c mice were used at test doses of 100, 200 and 300mg/kg body weight intra peritoneally (i.p. Results In yeast induced pyrexia, VBME demonstrated dose dependently (78.23% protection at 300mg/kg, similar to standard drug, paracetamol (90% at 150mg/kg i.p. VBME showed a dose dependent analgesia in various pain models i.e. acetic acid, hot plat and tail immersion having 78.90%, 69.96% and 68.58% protection respectively at 300mg/kg. However, the analgesic action of VBME was completely antagonized by the injection of naloxone like opiate antagonists. Similarly carrageenan and histamine induces inflammation was significantly antagonized by VBME, 66.30% and 60.80% respectively at 300mg/kg. Conclusions It is concluded that VBME has marked antipyretic, analgesic and anti-inflammatory activities in various animal models and this strongly supports the ethnopharmacological uses of Viola betonicifolia as antipyretic, analgesic and anti-inflammatory plant.

This study aimed to compare 50 mg dexketoprofen vs. 1 g paracetamol that were parenterally administered before endoscopic retrograde cholangiopancreatography (ERCP) under sedoanalgesia with comparable anaesthesia depth regarding haemodynamic, pain, narcotic analgesic requirement, recovery and post-procedural cognitive functions. Overall, 80 ASA I-III patients aged 18-75 years who were undergoing scheduled ERCP were randomly assigned into three groups. In all patients, the mini-mental test (MMT) was conducted before the procedure. No drug was administered to controls (Group C; n=26); patients were transferred to ERCP unite 30 min after parenteral dexketoprofen (50 mg) in group D (n=27) and paracetamol (1 g) in group P (n=27). The standard monitoring was applied. After intravenously administering loading doses of midazolam (0.02 mgkg) and propofol (1 mg kg(-1)), propofol infusion was administered at a dose of 2-4 mg kg(-1) h(-1) to maintain a bispectral index value of 50-70. Fentanyl (0.05 μg kg(-1)) was intravenously administered when patients experienced pain. Haemodynamic effects, additional analgesic requirement, adverse effects during procedure, time to reach Aldrete score of 9 and satisfaction of an endoscopist and patient were recorded. MMT was repeated 3 h after completing the procedure. Fentanyl requirement during the procedure was significantly low in group D (pdexketoprofen provided better haemodynamic effect and pain control, thereby decreasing incidence of adverse events by reducing the requirement for narcotic analgesics.

Tamper-resistant prescription forms for narcotics in France:should we generalise them?

Science.gov (United States)

Daveluy, Amélie; Sauvaget, Lucie; Bastien, Angela; Lapeyre-Mestre, Maryse; Collin, Cédric; Richard, Nathalie; Haramburu, Françoise

2018-03-27

In France, prescription of narcotics must be written on a tamper-resistant prescription form with specific technical particularities. Dosage and daily dose of medicines shall be written out entirely in letters. These prescription forms are also mandatory for buprenorphine, clorazepate, clonazepam, tianeptine, buccal midazolam and zolpidem owing to traffic, abuse or diversion. In 2012, to assess the use of standard and tamper-resistant prescription forms and the acceptability of the generalization of the latter to all medicines, a national opinion survey was performed, with a postal questionnaire, within 3 randomized samples of 1,500 prescribers (physicians, dentists and midwives). Of the 403 participating prescribers (participation rate of 26.8%), 373 were physicians, 14 dentists and 16 midwives. Tamper-resistant prescription forms were used by 76.2% of prescribers, but only by 5.1% in a computerised version, whereas, for standard prescription forms, 61% used computer assisted prescription software. The main reason was the inability of the prescription software to print these forms or to respect the mandatory prescription rules for narcotics. Theft and falsification of prescriptions had ever occurred (working life). Most prescribers (62.5%) were against the generalization of tamper-resistant prescription forms. Those in favour were for a generalization to all medicines (65%) and not only to psychotropic agents. Generalization of tamper-resistant prescription forms is not a consensual solution to prevent medicines' diversion. Some prescribers alluded to the possibility of dematerialisation and electronic transmission of prescription forms, which could avoid theft, forgery or falsification.

2015-01-01

Full Text Available Background: Analgesics such as Ibuprofen and Paracetamol, which are clinically used for the treatment of fever and/or pain, are among the most frequently used pediatric medicines. However, the properties of these preparations determine their cariogenic and erosive potential. Aims: The main objective of this study was to analyze the pH, viscosity and total sugar content in a variety of Syrian pediatric liquid analgesics (PLA. Setting and Design: A total of 16 available liquid analgesics that belong to the Paracetamol and Ibuprofen group were analysed. Materials and Methods: The endogenous pH was measured using a digital pH meter, the viscosity was measured using a digital rotational viscometer and the total sugar content was performed according to Fehling method. Statistical Analysis: Data were presented by means of descriptive statistics (mean, standard deviation, minimum and maximum values. Results: The mean endogenous pH of PLA was 4.63 ± 0.57 ranging between 3.93 and 5.68, and almost all of analgesics (93.8% had pH values ≤5.5. The mean viscosity of PLA was 243.56 ± 186.6 cP and varied between 20.5 cP and 640.5 cP. Sugars were detected in 11 (68.75% analgesics, and varied considerably among sugar-containing analgesics from 5.38 to 69.4 (g/100 mL with a mean concentration of 24.97 ± 23.24 g/100 mL. Conclusion: PLA are potentially cariogenic and erosive because of low pH, high viscosity and high total sugar content. This may increase our concerns about the dental health of children who take liquid analgesics frequently or when long-term treatment is indicated.

2015-01-01

Full Text Available Background and Aims: Transversus abdominis plane (TAP block is suitable for operations where parietal pain is a major cause of pain. Renal transplant recipients are ideally suited to gain maximum benefit from TAP block as the incision classically involves the lower abdomen. This study was conducted to evaluate the analgesic efficacy of continuous TAP block in transplant recipients. Material and Methods: In a prospective double-blind study, 40 chronic renal failure patients undergoing open renal transplant were randomly divided into two groups. At the end of surgery during closure, a multiorifice epidural catheter was placed in TAP plane. Study group (Group S received Inj bupivacaine bolus 1 mg/kg (0.25% followed by infusion 0.25 mg/kg (0.125% through the catheter, whereas control group (Group C received normal saline through the catheter. Inj pentazocine (0.3 mg/kg was given as rescue analgesic at visual analogue score (VAS > 3 in any group at rest or on movement. The analgesic efficacy was judged by VAS, time of first rescue analgesic, and total analgesic consumption in 24 h. Results: Patients in Group S had significant lower VAS scores, longer time to first rescue analgesic (270 ± 347.96 vs. 42.85 ± 32.27 min and lower pentazocine consumption (9.75 ± 13.95 vs. 56.42 ± 12.46 mg in 24 h. There was significant sedation in Group C. Conclusion: The TAP catheter technique for postoperative pain control after renal transplant has proved to be effective in relieving the postoperative pain after renal transplant with less pentazocine requirement and less sedation.

Buddleja crispa Benth (Buddlejaceae) is a dense shrub; several species of genus Buddleja have been used in the management of various health conditions including pain and inflammation. The present study was aimed to investigate the analgesic, anti-inflammatory and anti-platelet properties of B. crispa. Male rats (220-270 gm,) and mice (25-30 gm) were randomly divided into different groups (n = 6). Various doses of plant extract of B. crispa, its fractions and pure compounds isolated from the plant were administered intraperitoneally (i.p). The analgesic, anti-inflammatory and anti-platelet activities were assessed using acetic acid and formalin-induced nociception in mice, carrageenan-induced rat paw edema and arachidonic acid-induced platelets aggregation tests. The intraperitoneal administration of the methanolic extract (50 and 100 mg/kg), hexane fraction (10 and 25 mg/kg i.p) exhibited significant inhibition (P < 0.01) of the acetic acid-induced writhing in mice and attenuated formalin-induced reaction time of animals in second phase of the test. Pure compounds BdI-2, BdI-H3 and BH-3 isolated from B. crispa produced significant (P < 0.01) analgesic activity in acetic acid-induced and formalin tests. The crude extract of B. crispa (50-200 mg/kg i.p.) and its hexane fraction inhibited carrageenan-induced rat paw edema with maximum inhibition of 65 and 71% respectively (P < 0.01). The analgesic and anti-inflammatory effect of the plant extract and isolated pure compounds were comparable to diclofenac sodium. B. crispa plant extract (0.5-2.5 mg/mL) produced significant anti-platelet effect (P < 0.01) with maximum inhibition of 78% at 2.5 mg/ml. The findings from our present study suggest that B. crispa possesses analgesic, anti-inflammatory and anti-platelet properties. B. crispa could serve a potential novel source of compounds effective in pain and inflammatory conditions.

Full Text Available Abstract Background Use of phenacetin and other analgesic and non-steroidal anti-inflammatory drugs (NSAIDs potentially influences bladder cancer incidence, but epidemiologic evidence is limited. Methods We analyzed data from 376 incident bladder cancer cases and 463 controls from a population-based case-control study in New Hampshire on whom regular use of analgesic drugs and NSAIDs was obtained. Odds ratios and 95% confidence intervals were computed using logistic regression with adjustment for potentially confounding factors. Separate models by tumor stage, grade and TP53 status were conducted. Results We found an elevated odds ratio (OR associated with reported use of phenacetin-containing medications, especially with longer duration of use (OR >8 years = 3.00, 95% confidence interval (CI = 1.4–6.5. In contrast, use of paracetamol did not relate overall to risk of bladder cancer. We also found that regular use of any NSAID was associated with a statistically significant decrease in bladder cancer risk (OR = 0.6, 95% CI = 0.4–0.9, and specifically use of aspirin. Further, the association with NSAID use was largely among invasive, high grade and TP53 positive tumors. Conclusion While these agents have been investigated in several studies, a number of questions remain regarding the effects of analgesic and NSAID use on risk of bladder cancer.

Pentanisia prunelloides is a medicinal plant widely used to remedy various ailments including infections, fever and rheumatism in Eastern Cape Province of South Africa. There is scanty report on the phytochemical and biological properties of the plant; hence various solvent extracts of the dried plant materials were phytochemically screened, and its aqueous extract evaluated for acute toxicity effect, analgesic and antiinflammatory properties in rodents. Different extracts of both leaf and rhizome were obtained separately with ethanol, methanol and water. Portions of the filtrate were used for qualitative screening of secondary metabolites and remaining portions were concentrated and dried. Dried grounded leaf and rhizome of the plant were also used for quantitative screening for some major components. The aqueous extract of the leaf and rhizome were used for acute toxicity (LD 50 ) test, antiinflammatory and analgesic activities in rodents. The qualitative phytochemical screening showed the presence of several phytoconstituents with saponins, flavonoids and alkaloids constituting highest constituents in the leaf and rhizome. The LD50: of the aqueous extracts (from leaf or rhizome) was found to be ≥5000 mg/kg orally. The leaf and rhizome aqueous extract (250-500 mg/kg) significantly (pphytochemicals which could be associated with their medicinal uses. The aqueous leaf and rhizome extracts are similarly non-toxic orally, showed antiinflammatory and analgesic potentials thus rationalizing its use in folkloric medicine.

BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) and analgesics are the most commonly used drugs and are increasingly available over-the-counter (OTC). In certain groups of patients, including kidney transplant recipients, their use may be complicated by adverse effects or drug interactions. The aim of our study was to assess the causes and frequency of OTC NSAIDs or analgesics use, as well as the awareness of related side effects. MATERIAL AND METHODS We enrolled 94 randomly selected kidney transplant recipients, who represented 5% of all kidney transplant recipients at our center. An anonymous survey consisting of 23 multiple-choice questions was administered voluntarily and anonymously. RESULTS In all, 63% of study patients confirmed taking the OTC painkillers; 22% of these patients took these drugs at least several times a week, and 4% took these drugs daily. For 38% of the study kidney transplant recipients, NSAIDs or analgesics were reported to be the only way to manage their pain. In addition, 30% of study patients were unaware of the risks associated with these drugs, despite the fact that 89% of the study patients consider physicians the best source of information. CONCLUSIONS Our study found that 63% of kidney transplant recipients regularly took OTC painkillers and 30% were unaware of the potential adverse effects. This necessitates continuous, ongoing education of kidney transplant recipients about the risks of OTC NSAIDs or analgesics use.

Exposure to various types of electromagnetic fields (EMFs) affects pain specificity (nociception) and pain inhibition (analgesia). Previous study of ours has shown that exposure to the resonant spectra derived from biologically active substances' NMR may induce to live targets the same effects as the substances themselves. The purpose of this study is to investigate the potential analgesic effect of the resonant EMFs derived from the NMR spectrum of morphine. Twenty five Wistar rats were divided into five groups: control group; intraperitoneal administration of morphine 10 mg/kg body wt; exposure of rats to resonant EMFs of morphine; exposure of rats to randomly selected non resonant EMFs; and intraperitoneal administration of naloxone and simultaneous exposure of rats to the resonant EMFs of morphine. Tail Flick and Hot Plate tests were performed for estimation of the latency time. Results showed that rats exposed to NMR spectrum of morphine induced a significant increase in latency time at time points (p spectrum of morphine. Our results indicate that exposure of rats to the resonant EMFs derived from the NMR spectrum of morphine may exert on animals similar analgesic effects to morphine itself.

Full Text Available Electroacupuncture (EA is a complementary therapy to improve morphine analgesia for postoperative pain, but underlying mechanism is not well-known. Herein, we investigated EA-induced analgesic effect in a plantar incision (PI model in male Sprague-Dawley rats. PI was performed at the left hind paw. EA of 4 Hz and high intensity or sham needling was conducted at right ST36 prior to PI and repeated for another 2 days. Behavioral responses to mechanical and thermal stimuli, spinal phospho-ERK, and Fos expression were all analyzed. In additional groups, naloxone and morphine were administered to elucidate involvement of opioid receptors and for comparison with EA. EA pretreatment significantly reduced post-PI tactile allodynia for over 1 day; repeated treatments maintained analgesic effect. Intraperitoneal naloxone could reverse EA analgesia. Low-dose subcutaneous morphine (1 mg/kg had stronger inhibitory effect on PI-induced allodynia than EA for 1 h. However, analgesic tolerance appeared after repeated morphine injections. Both EA and morphine could equally inhibit PI-induced p-ERK and Fos inductions. We conclude that though EA and morphine attenuate postincision pain through opioid receptor activations, daily EA treatments result in analgesic accumulation whereas daily morphine injections develop analgesic tolerance. Discrepant pathways and mechanisms underlying two analgesic means may account for the results.

To explore global changes in the prescription of analgesic drugs over time in the international long-term care (LTC) population. Systematic review. We included original research articles in English, published and unpublished, that included number of participants, country and year(s) of data collection, and prescription of analgesics (analgesics not otherwise specified, opioids, acetaminophen; scheduled only, or scheduled plus as needed (PRN)). LTC residents. We searched PubMed, EMBASE, CINAHL, International Pharmaceutical Abstracts, PsycINFO, Cochrane, Web of Science, Google Scholar, using keywords for LTC facilities and analgesic medication; hand-searched references of eligible papers; correspondence. Studies were quality rated using an adapted Newcastle-Ottawa scale. Pearson correlation coefficients were generated between percentage of residents prescribed an analgesic and year of data collection. If available, we investigated changes in acetaminophen and opioid prescriptions. Forty studies met inclusion criteria. A moderate correlation (0.59) suggested that scheduled prescription rates for analgesics have increased over time. Similar findings were reflected in scheduled prescriptions for acetaminophen and opioids. No increase was seen when analyzing scheduled plus PRN analgesics. Use of opioids (scheduled plus PRN) appears to have increased over time. Worldwide, use of opioids and acetaminophen has increased in LTC residents. Research is needed to explore whether this reflects appropriate pain management for LTC residents and if PRN medication is used effectively. © 2017 The Authors.

Full Text Available Non-steroidal anti-inflammatory drugs (NSAIDs have been successfully used for the alleviation of pain and inflammation in the past and continue to be used daily by millions of patients worldwide. However, gastrointestinal (GI toxicity associated with NSAIDs is an important medical and socioeconomic problem. Local generation of various reactive oxygen species plays a significant role in the formation of gastric ulceration associated with NSAIDs therapy. Co-medication of antioxidants along with NSAIDs has been found to be beneficial in the prevention of GI injury. This paper describes the synthesis and biological evaluation of N-1-(phenylsulfonyl-2-methylamino-substituted-1H-benzimidazole derivatives as anti-inflammatory analgesic agents with lower GI toxicity. Studies in vitro and in vivo demonstrated that the antioxidant activity of the test compounds decreased GI toxicity.

Full Text Available Abstract Simultaneous bilateral femoral neck fractures are extremely rare and associated with various conditions. Up to now Most cases had correlations with major trauma, repetitive minor trauma, seizure, parathyroid or renal dysfunction, anti-epileptic medications, seizure, etc. A 28-year-old addict man referred to us with a 10-year history of narcotic drug abuse and history of 8 months bilateral groin pain. He admitted with displaced bilateral femoral neck fracture. Because of long duration of this condition and osteonecrosis revealed on bone scan, one-staged bilateral hip hemiarthroplasty was done. A good function was noted after surgery to 4-month follow up. Up to now, have not be founded in the literature that a case of bilateral femoral neck fracture associated with narcotic drug abuse. Because of negative effects of opium or smoking on bone tissues, a simple bone pain should aware us about the risk of stress or fatigue fracture.

Objective: To explore experiences and opinions of patients about sharing prescription analgesics, reasons for sharing prescription analgesics, the way in which patients choose to share those medications, their awareness of risk regarding sharing prescription analgesics, and how they estimated the potential risk.Methods: This qualitative study was conducted by focus group discussions with 40 participants led by a moderator trained in focus group methodology using a semi-structured moderator guide. Adults aged ≥18 years who had received a prescription for an analgesic at least once in a lifetime were included. Six separate focus groups were conducted to discuss participants’ perception of risks associated with sharing of prescription analgesics among patients. Additionally, participants filled out two questionnaires on demographic data, their own behavior regarding sharing analgesics, and their attitudes about risks associated with sharing prescription analgesics.Results: In a questionnaire, 55% of the participants indicated that they personally shared prescription analgesics, while subsequently in the focus group discussions, 76% confessed to such behavior. Participants recognized certain risks related to sharing of prescription analgesics, mentioned a number of reasons for engaging in such behavior, and indicated certain positive

Hospitalized patients often experience adverse events of the gastrointestinal tract due to analgesic treatment. The objectives of this study were to estimate use of medications for treatment of nausea, vomiting, or constipation (NVC medications) after initiation of analgesic treatment, and to compare differences in length of stay and treatment costs between patients who received NVC medications and those who did not. This retrospective cohort study used the Premier Perspective data from January 1, 2005 to December 31, 2007 and stratified inpatients into 4 groups based on the first analgesic agent they were given. Patients were observed for 14 days after the first analgesic use until a regimen change, first use of NVC medication, or hospital discharge, whichever occurred first. Data were analyzed using a Cox proportional hazards model and a generalized linear model. This study found that 239,183 (55.1%) of 434,304 patients received NVC medications after analgesic administration. Compared with oral nonopioid analgesics, the risk of using NVC medication was 4.8 times higher for injectable opioid analgesics after controlling for confounders. Patients who received NVC medications were hospitalized 0.26 days longer (P hospital resources.

We instituted a ketamine-predominant analgesic regimen in the peri- and postoperative periods to limit the effects of narcotic analgesia on bowel function in patients undergoing radical cystectomy. The primary end points of interest were time to return of bowel function, time to discharge, and efficacy of the analgesic regimen. We performed a retrospective chart review of patients undergoing robotic-assisted laparoscopic cystectomy (RARC) with urinary diversion by a single surgeon at our institution from January 1, 2011 to June 30, 2012. Patients receiving the opioid-minimizing ketamine protocol were compared to a cohort of patients undergoing RARC with an opioid-predominant analgesic regimen. In total, 15 patients (Group A) were included in the ketamine-predominant regimen and 25 patients (Group B) in the opioid-predominant control group. Three patients (19%) in Group A discontinued the protocol due to ketamine side effects. The mean time to bowel movement and length of stay in Group A versus Group B was 3 versus 6 days (p return of bowel function and length of hospitalization after RARC. Our study has its limitations as a retrospective, single surgeon, single institution study and the non-randomization of patients. Notwithstanding these limitations, this study was not designed to show inferiority of one approach, but instead to show that our protocol is safe and efficacious, warranting further study in a prospective fashion.

The aim of this study was to identify the impact of ethnicity and language on parental attitudes regarding analgesic use to treat children's pain. A total of 206 parents of children undergoing outpatient surgery were recruited to complete the Medication Attitudes Questionnaire, a measure of parental beliefs about using analgesic medications to treat children's pain. Parents were grouped into one of 3 categories according to ethnicity and primary language spoken: English-speaking white, English-speaking Hispanic, and Spanish-speaking Hispanic. Group differences in pain medication attitudes were examined. After controlling for socioeconomic status, English-speaking Hispanic parents endorsed higher levels of misconceptions about pain medication use, including a tendency to avoid analgesic use for children, compared with English-speaking white and Spanish-speaking Hispanic parents. This study highlights parental characteristics, including ethnicity and language, which may place children at higher risk for undertreatment of acute pain based on misconceptions about analgesic use for children. Specifically, English-speaking Hispanic parents may be most likely to undertreat children's pain at home. Future studies are needed to identify the most appropriate means of providing education to counter parental misconceptions and support optimal pain management of children's pain in the home setting.

Screening of Alkaloidal Fraction of Conium maculatum L. Aerial Parts for Analgesic and Antiinflammatory Activity.

Science.gov (United States)

Madaan, Reecha; Kumar, S

2012-09-01

Conium maculatum Linn. (Umbelliferae) has been traditionally used in the treatment of spasmodic disorders, and to relieve nervous excitation, rheumatic pains in the old and feeble, pain in stomach, pain of gastric ulcer, nervousness and restlessness. Alkaloids have long been considered as bioactive group of constituents present in C. maculatum. Despite a long tradition of use, C. maculatum has not been evaluated pharmacologically to validate its traditional claims for analgesic and antiinflammatory activities. Thus, the present investigations were undertaken with an objective to evaluate alkaloidal fraction of C. maculatum aerial parts for analgesic and antiinflammatory activities. Test doses (100 or 200 mg/kg, p.o.) of alkaloidal fraction were evaluated for analgesic activity using tail flick test and antiinflammatory activity using carrageenan-induced paw oedema test in rats. Morphine (5 mg/kg, p.o.) and indomethacin (5 mg/kg, p.o.) were used as standard analgesic and antiinflammatory drugs, respectively. Alkaloidal fraction of the plant exhibited significant analgesic activity at a dose of 200 mg/kg as it showed significant increase in tail flicking reaction time with respect to the control during 2 h intervals of observation. It also exhibited significant antiinflammatory activity at a dose of 200 mg/kg as it inhibited paw oedema in rats to 71% and reduced the paw volume one-fourth to the control during 1(st) h of the study. The present investigations suggest that alkaloids are responsible for analgesic and antiinflammatory activities of C. maculatum.

Then, we examine in more detail the emerging evidence for the potential impact of analgesic use on cancer risk and disease progression. Increasing findings suggest that long-term use of nonsteroidal anti-inflammatory drugs, particularly aspirin, may reduce cancer occurrence. However, acetaminophen may raise the risk of some hematological malignancies. Drugs acting upon receptors of gamma-aminobutyric acid (GABA and GABA “mimetics” (eg, gabapentin appear generally safe for cancer patients, but there is some evidence of potential carcinogenicity. Some barbiturates appear to slightly raise cancer risks and can affect cancer cell behavior in vitro. For cannabis, studies suggest an increased risk of squamous cell carcinoma of the tongue, larynx, and possibly lung. Morphine may stimulate human microvascular endothelial cell proliferation and angiogenesis; it is not clear whether this might cause harm or produce benefit. The opioid, fentanyl, may promote growth in some tumor cell lines. Opium itself is an emerging risk factor for gastric adenocarcinoma and possibly cancers of the esophagus, bladder, larynx, and lung. It is concluded that analgesics currently prescribed for cancer pain can

The present study was aimed to evaluate the analgesic properties of Urtica dioica (UD) and to profile phytochemicals by gas chromatography-mass spectrometry (GC-MS). The ethanolic extracts were prepared by maceration method and extraction using rotary evaporator. The analgesic activity was analysed by hot plate method, formalin test, acetic acid-induced writhing test and the tail-flick test with different doses of the ethanolic extract. In all tests, the leaf's ethanolic extract exhibited significant analgesic activity (p analgesic activity with many tests. The GC-MS analysis of the ethanol extract of leaf revealed many compounds; 2-methyltetradecane dodecane, 2,6,11-trimethyl-; 2,6,11-trimethyldodecane, and trimethylhexane which are pharmaceutically the most important. These findings justify that UD can be a valuable natural analgesic source which seemed to provide potential phototherapeutics against various ailments. The analysis of ethanolic extract of UD by GCMS revealed the presence of several compounds including polyphenols, flavonoids, triterpenes which can explain the analgesic effect of UD and its mechanism of action. Hence, UD could be another therapeutic alternative for relieving pain and for minimising the use of drugs that have long-term secondary effects.

To compare the postoperative analgesic effects of intra-articular levobupivacaine with bupivacaine following knee arthroscopy. Forty patients, aged between 20-60 years and undergoing elective knee arthroscopy were enrolled into the study protocol that was carried out in Tepecik Education and Research Hospital, Izmir, Turkey between January and June 2007. General anesthesia protocol was the same in all patients. At the end of surgery, the patients were randomly assigned into 2 groups (n=20 in each group). Group L received 20 ml 0.5% levobupivacaine and Group B received 20 ml 0.5% bupivacaine intra-articularly. We evaluated the level of postoperative pain (by visual analoque scale at 1, 2, 4, 6, 12, and 24 hours after surgery), first analgesic requirement time (period measured from the end of the surgery until further analgesia was demanded), and total analgesic consumption during 24 hours. There were no significant difference in the postoperative pain scores of the patients between groups. The first analgesic requirement times were not statistically different. Twelve patients in Group L (60%) and 9 patients in Group B (45%) needed no additional analgesic during the 24 hours (p>0.05). No complications and side effects were found related to the intra-articular treatment. The results of the study show that intra-articular 20 ml 0.5% levobupivacaine provides effective analgesia comparable to that provided by 20 ml 0.5% bupivacaine. (author)

Evaluation of Analgesic Activity of Papaver libanoticum Extract in Mice: Involvement of Opioids Receptors

Directory of Open Access Journals (Sweden)

Mohamad Ali Hijazi

2017-01-01

Full Text Available Papaver libanoticum is an endemic plant to Lebanese region (family Papaveraceae that has not been investigated before. The present study aimed to explore the analgesic activity of dried ethanolic extract of Papaver libanoticum (PLE using tail flick, hot plate, and acetic acid induced writhing models in mice. The involvement of opioid receptors in the analgesic mechanism was investigated using naloxone antagonism. Results demonstrated that PLE exhibited a potent dose dependent analgesic activity in all tested models for analgesia. The analgesic effect involved activation of opioid receptors in the central nervous system, where both spinal and supraspinal components might be involved. The time course for analgesia revealed maximum activity after three hours in both tail flick and hot plate methods, which was prolonged to 24 hours. Metabolites of PLE could be responsible for activation of opioid receptors. The EC50 of PLE was 79 and 50 mg/kg in tail flick and hot plate tests, respectively. The total coverage of analgesia by PLE was double that of morphine in both tests. In conclusion, PLE proved to have opioid agonistic activity with a novel feature of slow and prolonged effect. The present study could add a potential tool in the armaments of opioid drugs as a natural potent analgesic and for treatment of opioid withdrawal syndrome.

To date, no system has been published that allows investigators to adjust for the overall sedative and/or analgesic effects of medications, or changes in medications, in clinical trial participants for whom medication use cannot be controlled. This is common in clinical trials of behavioral and complementary/alternative therapies, and in research involving elderly or chronically ill patients for whom ongoing medical care continues during the trial. This paper describes the development, and illustrates the use, of a method we developed to address this issue, in which we generate single continuous variables to represent the daily sedative and analgesic loads of multiple medications. Medications for 90 study participants in a clinical trial of a nonpharmacological intervention were abstracted from medication administration records across multiple treatment periods. An expert panel of three academic clinical pharmacists and a geriatrician met to develop a system by which each study medication could be assigned a sedative and analgesic effect rating. The two measures, when applied to data on 90 institutionalized persons with Alzheimer's disease, resulted in variables with moderately skewed distributions that are consistent with the clinical profile of analgesia and sedation use in long-term care populations. The average study participant received 1.89 analgesic medications per day and had a daily analgesic load of 2.96; the corresponding figures for sedation were 2.07 daily medications and an average daily load of 11.41. A system of classifying the sedative and analgesic effects of non-study medications was created that divides drugs into categories based on the strength of their effects and assigns a rating to express overall sedative and analgesic effects. These variables may be useful in comparing patients and populations, and to control for drug effects in future studies.

A series of Schiff bases 1-17 were synthesised by way of a facile condensation between 1-amino-anthraquinone with a variety of carbonyl compounds in the presence of a catalytic amount of dodeca-tungstosilicic acid/P 2O5 under solvent free conditions at room temperature. These were charachterised by1H- and 13C-NMR, LCMS, FTIR and elemental analyses. All the compounds were screened for their analgesic activity using hot plate thermal stimuli method at dose of 10 and 30 mg/kg. Diclofenac sodium was used as a reference drug. All the compounds at dose of 10 and 30 mg/kg body weight showed the significant (p<0.05) increase in latency time as compared to control (normal saline). Compound 5 showed excellent activity after 120 min of drug administration (10 mg/kg) of body weight. Compound 10 was found to be potent (10.48+-1.19s, 11.27+-1.2s and 10.24+-1.9s) at dose of 30 mg/kg at 30, 60 and 120 min, respectively when compared to the standard drug. Compound 6 (10.13+-0.4s) was also found to be an excellent analgesic compound at a dose of 30 mg/kg at 120 min. However, the studies on analgesic activity revealed that some of the target compounds may be strong candidates as an analgesic drug. (author)

It is reported that ketamine, a N-methyl-D-aspertate (NMDA) receptor antagonist, can provide analgesic effect improving postoperative pain management and decrease the supplementary analgesic requirement. We investigated the analgesic sparing effect of ketamine for postoperative pain in children undergoing surgery of body surface. Fifty eight patients (0-9 yrs) who had surgery of body surface were divided into two groups (ketamine : n = 27, Group K or control : n = 31, Group N). Postoperative analgesia extracted from charts was retrospectively evaluated by the times patients used analgesics until discharge after the operations. Chi-square and Mann-Whitney U tests were used for statistical analysis. Results : The ketamine group received an intrave- nous bolus of ketamine (1 mg - kg-1) before surgical skin incision. However, there were no significant differ- ences of usage (Group K vs Group N : 4/27 vs 7/31, P=0.45) and frequency of supplementary analgesic us- ages (P=0.85) among groups. In addition, there were also no significant demographic differences between the two groups. Conclusions : Our investigation suggests that the intravenous bolus of ketamine (1 mg - kg-1) before surgical skin incision does not decrease the supple- mentary analgesic requirements on postoperative pain management in pediatric surgery of the body surface.

Opioid analgesic overdose mortality continues to rise in the United States, driven by increases in prescribing for chronic pain. Because chronic pain is a major indication for medical cannabis, laws that establish access to medical cannabis may change overdose mortality related to opioid analgesics in states that have enacted them. To determine the association between the presence of state medical cannabis laws and opioid analgesic overdose mortality. A time-series analysis was conducted of medical cannabis laws and state-level death certificate data in the United States from 1999 to 2010; all 50 states were included. Presence of a law establishing a medical cannabis program in the state. Age-adjusted opioid analgesic overdose death rate per 100 000 population in each state. Regression models were developed including state and year fixed effects, the presence of 3 different policies regarding opioid analgesics, and the state-specific unemployment rate. Three states (California, Oregon, and Washington) had medical cannabis laws effective prior to 1999. Ten states (Alaska, Colorado, Hawaii, Maine, Michigan, Montana, Nevada, New Mexico, Rhode Island, and Vermont) enacted medical cannabis laws between 1999 and 2010. States with medical cannabis laws had a 24.8% lower mean annual opioid overdose mortality rate (95% CI, -37.5% to -9.5%; P = .003) compared with states without medical cannabis laws. Examination of the association between medical cannabis laws and opioid analgesic overdose mortality in each year after implementation of the law showed that such laws were associated with a lower rate of overdose mortality that generally strengthened over time: year 1 (-19.9%; 95% CI, -30.6% to -7.7%; P = .002), year 2 (-25.2%; 95% CI, -40.6% to -5.9%; P = .01), year 3 (-23.6%; 95% CI, -41.1% to -1.0%; P = .04), year 4 (-20.2%; 95% CI, -33.6% to -4.0%; P = .02), year 5 (-33.7%; 95% CI, -50.9% to -10.4%; P = .008), and year 6 (-33.3%; 95% CI, -44.7% to

Pain evaluation in large community studies is difficult. Analgesics can be a useful tool in estimating pain-related conditions in which analgesic use is highly regulated. In this study, we evaluated analgesics consumption patterns of regular Israel Defense Force soldiers. We have performed a historical cohort study of 665,137 young adults during active duty in 2002 to 2012. Analgesics were prescribed to 518,242 (78%) soldiers, mostly for musculoskeletal pain (69.3%), abdominal pain (12.7%), and headache (12.1%). Acute (1-14 days), subacute (15-90), and chronic (>90 days) analgesic use episodes were experienced by 396,987 (59.7%), 74,591 (11.2%), and 46,664 (7%) of the population. In a multivariate model, predictors for chronic analgesics use were as follows: low intelligence, service in a combat supporting unit, previous pain diagnosis, male sex, Israeli nativity, low socioeconomic status, and high body mass index. Low intelligence had the highest odds ratio for chronic analgesic consumption (2.1) compared with other predictors. Chronic analgesic use was associated with a significant increase in health care utilization cost per year (911$ per soldier vs 199$ for nonusers), increased sick leave days per year (7.09 vs 0.67 for nonusers), and higher dropout rate from combat units (25% vs 9.2% for nonusers). Chronic use of analgesics is common among young adults, and it is an important predictor for unsuccessful military service and high health care utilization costs. Further studies in other setups are indicated.

Full Text Available Bone pain is a common and severe symptom in cancer patients. The present study employed a mouse model of leukemia bone pain by injection K562 cells into tibia of mouse to evaluate the analgesic effects of lappacontine. Our results showed that the lappaconitine treatment at day 15, 17 and 19 could effectively reduce the spontaneous pain scoring values, restore reduced degree in the inclined-plate test induced by injection of K562 cells, as well as restore paw mechanical withdrawal threshold and paw withdrawal thermal latency induced by injection of K562 cells to the normal levels. Additionally, the molecular mechanisms of lappaconitine’s analgesic effects may be related to affect the expression levels of endogenous opioid system genes (POMC, PENK and MOR, as well as apoptosis-related genes (Xiap, Smac, Bim, NF-κB and p53. Our present results indicated that lappaconitine may become a new analgesic agent for leukemia bone pain management.

N-aryl derivatives of phthalimide and 4-nitro phthalimide have demonstrated cyclooxygenase inhibitory activity. Also they possess an excellent analgesic and anti-inflammatory activity. In this work, a new series of N-arylmethylideneamino derivatives of phthalimide and 4-nitro phthalimide were designed and synthesized. The designed compounds were synthesized by condensation of the appropriate aldehyde and N-aminophthalimide in ethanol at room temperature at PH around 3. Their analgesic and anti-inflammatory activity were evaluated by acetic acid-induced pain test and carrageenan-induced paw edema test in mice and rats, respectively. The details of the synthesis and chemical characterization of the analogs are described. In vivo screening showed compounds 3a, 3b, 3f and 3h were the most potent analgesic compounds. In addition compounds 3a, 3c, 3d, 3e and 3j indicated comparable anti-inflammatory activity to indomethacin as reference drug.

This case study describes the effects of the use of curanderismo, an indigenous healing modality combining techniques in massage, sound, and aromatherapy, on a patient with chronic pain. Despite being a commonly used health practice in certain populations, little is reported in the medical literature about the use of curanderismo. Case report as part of a larger randomized trial of curanderismo for chronic pain. Setting was a community-based hospital affiliated primary care clinic. An adult patient with chronic, opioid dependent back pain following an injury, and subsequent spinal fusion was treated. Intervention was the patient received 33 curanderismo treatment sessions over 10 months in addition to ongoing conventional treatment at a community-based chronic pain management clinic. Main outcomes measures were self-reported assessments of pain, functional ability, mood, insomnia, and narcotic usage. Secondary outcome measure was qualitative interview. Although there was no change in quantitative self-reported pain measures, the patient reported improved function, mood, and sleep as well as decreased narcotic usage. Curanderismo, in addition to conventional pain management, improved patient reported symptoms and functional ability, led to healthy lifestyle changes, and decreased narcotic usage. Controlled studies are needed to confirm the benefit of curanderismo as safe, non-interventional, and cost-effective adjunct for chronic pain management. Copyright © 2016 Elsevier Inc.

We investigated the postoperative analgesic efficacy and effect on total tramadol consumption of intravenous dexketoprofen trometamol, a new nonsteroidal anti-inflammatory drug, in patients that had undergone lumbar disc surgery. Sixty patients were included in this placebo-controlled, randomized, double-blind study. General anesthesia was applied to both groups. Group D (n=30) received dexketoprofen (50 mg) intravenously 30 minutes before the end of surgery and at the postoperative 12th hour, whereas group C (n=30) received 2 mL of 0.9% NaCL intravenously at the same time points. All patients received a patient controlled analgesia device with a tramadol, 25 mg bolus, 15 minutes lockout protocol, and were followed with visual analog scale, verbal rating scale, modified Aldrete recovery scoring system, and Ramsay sedation scale in the postoperative period. There was no significant difference between the groups for demographic data, duration of surgery, mean arterial pressure, and heart rate. The time to first postoperative analgesic requirement was significantly longer in group D (151.33±81.98 min) than group C (19±5.78 min) (Pdexketoprofen was an effective analgesic for postdiscectomy pain when used alone or in addition to opioids. It is easy to administer and decreases tramadol consumption and opioid-related side effects.

Inflammations and immune-related diseases including rheumatoid arthritis are widespread in the entire globe. The treatment of these illnesses is mainly based on the use of synthetic and biotechnological drugs, in recent years. Tunisian traditional medicine is a potential source of new remedies namely Citrullus colocynthis Schrad. (Cucurbitaceae): endemic in southern Tunisia and used in folk medicine to treat many inflammation disorders. Our goal was to assess the in vivo analgesic and anti-inflammatory activities of Tunisian Citrullus colocynthis immature fruit and seed organic extracts (petroleum ether, chloroform, ethyl acetate, acetone and finely methanol extract). Yields of prepared organic extracts are gravimetrically determined. For the analgesic and anti-inflammatory activities, we have used respectively, the acetic acid writhing test in mice and the carrageenan-induced paw edema assay in rats. All extracts displayed an important analgesic and anti-inflammatory activities at different doses without inducing any side effects. This study has demonstrated the analgesic and anti-inflammatory activities of Citrullus colocynthis immature fruit and seed extracts. Experiment results provide scientific insight into the ancient practice of utilizing Citrullus colocynthis Schrad. as analgesic and as anti-inflammatory agents.

Analgesics are the most common self prescribed drugs. Although considered to be relatively safe, side effects are often seen when these drugs are used for prolonged period, in high doses or used where contraindicated. Majority of the consumers are not aware of the side effects. These days ample amount of information is available on web, it is important to explore its role in educating the population regarding the safe use of self prescribed analgesics. To explore pattern of analgesic use, to identify population at risk of developing side effects related to analgesic use, awareness of side effects and potential role of internet to bring awareness about safe use of self prescribed analgesic drugs in a rural area of Delhi. A cross-sectional survey based study was done on 500 adults in the age group of 18-65 years of Madanpur Khadar area of South Delhi, India. Data collection was done by conducting visits to pharmacy shops from the people who were buying drugs without prescription and taking face to face interviews using a semi-structured questionnaire. Statistical analysis was performed using descriptive tests with Microsoft office excel 2007. Results of our study showed that among all the self prescribed analgesics paracetamol (57%) was used most frequently followed by aspirin and other NSAIDs. It was found that 9.6% of the consumers were having associated co-morbid illness, 11.4% were simultaneously taking other drugs and 15.2% were alcoholics. Majority (65.4%) of the buyers were not aware about any kind of side effects of the analgesics. Internet friendly consumers were found to be 44%. Ability to use internet and education level were found to be directly related (r=0.802). The pattern of analgesic consumption in the rural population of Delhi shows that a large number of consumers may be at risk of developing side effects of self prescribed analgesics. The awareness about the side effects is limited. A significant number of consumers are internet friendly. Hence

Use of over-the-counter analgesics among adolescents has increased markedly. High consumption of over-the-counter analgesics among adolescents is associated with frequent pain, lower self-esteem, reduced sleep, lower educational ambition, binge drinking, higher caffeine consumption, and part-time employment. Knowledge about life experiences of adolescents who frequently use over-the-counter analgesics may be useful to prevent health problems. The purpose of the study was to increase knowledge about adolescents who suffer from frequent pain and have a high consumption of over-the-counter analgesics. A qualitative study, employing one-on-one, in-depth interviews using a thematic interview guide. Data were collected in Norway in 2013-2014. Three boys and sixteen girls; aged 14-16 years, who continuously consumed over-the-counter analgesics were recruited from ten high schools in urban and suburban districts. Candidate participants were excluded if they were medically diagnosed with an acute or chronic illness, requiring extended use of over-the-counter analgesics within the last year. The interviews were taped, transcribed and analysed as text according to Kvale's three contexts of interpretation: self-understanding, common sense and theory. All participants disclosed unresolved physical and psychosocial distress characterized as pain. Frequent pain from various body parts made everyday life challenging. Methods of pain self-appraisal and over-the-counter analgesics use often mimicked maternal patterns. Participants reported being raised under unpredictable circumstances that contributed to long lasting family conflicts and peer-group problems. Participants wanted to feel appreciated and to be socially and academically successful. However, pain reduced their ability to manage everyday life, hampered experienced possibilities for success, and made social settings difficult. Childhood experiences influence how adolescents experience pain and use over

Full Text Available Marasmius androsaceus is a medicinal fungus mainly used to treat various forms of pain in China. This study investigated the analgesic effects of an ethanol extract of M. androsaceus (MAE and its potential molecular mechanisms. Oral administration of MAE (50, 200, and 1000 mg/kg had significant analgesic effects in an acid-induced writhing test, a formalin test, and a hot-plate test, with effectiveness similar to tramadol (the positive control drug. The autonomic activity test showed that MAE had no harmful effects on the central nervous system in mice. MAE resulted in significantly enhanced levels of noradrenalin and 5-hydroxytryptamine in serum but suppressed both of these neurotransmitters in the hypothalamus after 30 s of hot-plate stimulation. Co-administration with nimodipine (10 mg/kg; a Ca2+ channel blocker strongly enhanced the analgesic effect in the hot-plate test compared to MAE alone. Moreover, MAE down-regulated the expression of calmodulin-dependent protein kinase II (CaMKII in the hypothalamus after a 30-s thermal stimulus. These results suggested that the analgesic ability of MAE is related to the regulation of metabolism by monoamine neurotransmitters and Ca2+/CaMKII-mediated signaling, which can potentially aid the development of peripheral neuropathic pain treatments obtained from M. androsaceus.

To analyze and characterize the intake profile of pain-relief drugs in a population-based study of adults with chronic low back pain (CLBP). EpiReumaPt was a cross-sectional Portuguese population-based study (10,661 subjects). Self-reported active CLBP was considered to be low back pain on the day of enrollment and for ≥ 90 days. Prevalence and profile of analgesic intake was characterized among those self-reporting active CLBP, taking into account the intensity of pain and the World Health Organization (WHO) analgesic ladder. We further investigated whether the presence of active CLBP was a factor independently associated with the intake of analgesics (adjusted for potential confounders). Among 1,487 subjects with active CLBP, only 18.7% were using analgesic/pain-relief drugs. Estimated prevalence was anxiolytics, 14.1%; nonsteroidal anti-inflammatory drugs (NSAIDs), 12.3%; antidepressants, 10.1%; analgesic, antipyretics, 6.6%; anticonvulsants, 3.4%; central muscle relaxants, 2.6%; and analgesic opioids, 1.6%. Most subjects with severe pain were in the first step of the WHO analgesic ladder: NSAIDs plus anxiolytics (4.6%), NSAIDs plus antidepressants (3.2%), or NSAIDs plus muscle relaxants (2.5%). The presence of active CLBP was significantly associated with the intake of all therapeutic groups: antidepressants (odds ratio [OR] = 12.56; P pain-relief drug intake in patients with active CLBP was very low, even for those with severe pain. The WHO analgesic ladder was carefully followed, with an extremely conservative use of analgesic opioids even for those with severe pain. © 2016 World Institute of Pain.

Butalbital, a barbiturate, is present in analgesic combinations used by headache sufferers. Overuse/abuse of these combinations may cause dependence, chronic migraine, and medication-overuse headache (MOH). MOH is difficult to manage: it improves interrupting analgesic overuse, but requires monitoring, because relapses are frequent. A gas chromatography-mass spectrometry (GC-MS) method for hair analysis has been developed and validated to document abuse of an analgesic combination containing butalbital and propyphenazone by a patient with MOH. For over ten years the patient managed her headache using eight suppositories/day of an analgesic combination containing butalbital 150mg, caffeine 75mg, and propyphenazone 375mg per suppository. An outpatient detoxification treatment was carried out. After three weeks, the patient reduced the consumption to one suppository/day. At the first control visit, after three months from the beginning of detoxification, the patient increased the use of the combination to four suppositories/day and at the second control visit, after seven months from the beginning of detoxification, she was back to eight suppositories/day. At the two control visits, a hair sample was taken for determination of butalbital and propyphenazone. Moreover blood and urine samples for determination of butalbital were drawn at the beginning of detoxification treatment and at the two control visits. With the segmental analysis of two hair samples the medication history of ten months could be estimated. In the first hair sample, collected at the first control visit, in the distal segment, butalbital and propyphenazone concentrations were, respectively, 17.5ng/mg and 56.0ng/mg, confirming the prolonged abuse; in the proximal segment, concurrently with the detoxification treatment, butalbital and propyphenazone concentrations had reduced respectively to 5.45ng/mg and 11.1ng/mg. The second hair sample, collected at the second control visit, proved the fair course

Full Text Available Pogostemon cablin (PC is a herbal medicine traditionally applied to treat not only common cold, nausea and diarrhea but also headache and fever. The aim of this study was to investigate the analgesic and anti-inflammatory properties of standardized PC methanol extract (PCMeOH in vivo. Investigations were performed in mice with two analgesic models. One was acetic acid-induced writhing response and the other formalin-induced paw licking. The anti-inflammatory effect was tested by λ-carrageenan (Carr-induced mice paw edema. These analgesic experimental results indicated that PCMeOH (1.0 g/kg decreased the acetic acid-induced writhing responses and PCMeOH (0.5 and 1.0 g/kg decreased the licking time in the second phase of the formalin test. Moreover, Carr-induced paw edema inflammation was significantly reduced in a dose-dependent manner when PCMeOH (0.5 and 1.0 g/kg was administered 3 and 4 h after the Carr injection. Mechanistic studies showed that PCMeOH decreased the levels of malondialdehyde in the edema paw by increasing the activities of anti-oxidant enzymes, such as superoxide dismutase, glutathione peroxidase and glutathione reductase, in the liver and decreasing the cyclooxygenase 2 and tumor necrosis factor-α activities in the edema paw. This study has demonstrated the analgesic and anti-inflammatory effects of PCMeOH, thus verifying its popular use in traditional medicine.

Pain is common in nursing home settings. To describe scheduled analgesic use among nursing home (NH) residents experiencing non-cancer pain and evaluate factors associated with scheduled analgesic use. We identified 2508 residents living in one of 185 NHs predominantly from one for-profit chain, with pain recorded on two consecutive Minimum Data Set assessments. Pharmacy transaction files provided detailed medication information. Logistic regression models adjusted for clustering of residents in NHs identified factors related to scheduled prescription analgesics. Twenty-three percent had no scheduled analgesics prescribed. Those with scheduled analgesics were more likely to have excruciating pain (5.5% vs. 1.2%) and moderate pain documented (64.7% vs. 47.5%) than residents without scheduled analgesics. Hydrocodone (41.7%), short-acting oxycodone (16.6%), and long-acting fentanyl (9.4%) were common, and 13.8% reported any nonsteroidal anti-inflammatory agent use. Factors associated with decreased odds of scheduled analgesics included severe cognitive impairment (adjusted odds ratio [AOR] 0.56; 95% confidence interval [CI] 0.36 to 0.88), age more than 85 years (AOR 0.57; 95% CI 0.41 to 0.80), and Parkinson's disease (AOR 0.55; 95% CI 0.30 to 0.99). Factors associated with increased odds of scheduled analgesic use included history of fracture (AOR 1.79; 95% CI 1.16 to 2.76), diabetes (AOR 1.30; 95% CI 1.02 to 1.66), and higher Minimum Data Set mood scores (AOR 1.11; 95% CI 1.04 to 1.19). Some improvements in pharmacologic management of pain in NHs have been realized. Yet, presence of pain without scheduled analgesics prescribed was still common. Evidence-based procedures to assure adherence to clinical practice guidelines for pain management in this setting are warranted. Copyright © 2013 U.S. Cancer Pain Relief Committee.

Chronic pain is common in the United States and prescribed opioid analgesics use for noncancer pain has increased dramatically in the past two decades, possibly accounting for the current opioid addiction epidemic. Co-morbid drug use in those prescribed opioid analgesics is common, but there are few data on polysubstance use patterns. We explored patterns of use of cigarette, alcohol, and illicit drugs in HIV-infected people with chronic pain who were prescribed opioid analgesics. We conducted a secondary data analysis of screening interviews conducted as part of a parent randomized trial of financial incentives to improve HIV outcomes among drug users. In a convenience sample of people with HIV and chronic pain, we collected self-report data on demographic characteristics; pain; patterns of opioid analgesic use (both prescribed and illicit); cigarette, alcohol, and illicit drug use (including cannabis, heroin, and cocaine) within the past 30 days; and current treatment for drug use and HIV. Almost half of the sample of people with HIV and chronic pain reported current prescribed opioid analgesic use (N = 372, 47.1%). Illicit drug use was common (N = 505, 63.9%), and cannabis was the most commonly used illicit substance (N = 311, 39.4%). In multivariate analyses, only cannabis use was significantly associated with lower odds of prescribed opioid analgesic use (adjusted odds ratio = 0.57; 95% confidence interval: 0.38-0.87). Conclusions/Importance: Our data suggest that new medical cannabis legislation might reduce the need for opioid analgesics for pain management, which could help to address adverse events associated with opioid analgesic use.

Analgesic efficacy of ultrasound-guided transverse abdominis plane block, administered a little more medially, just close to the origin of the transverse abdominis muscle has not yet been investigated in patients undergoing unilateral inguinal hernia repair. We hypothesised that medial transverse abdominis plane block would provide comparable postoperative analgesia to ilioinguinal-iliohypogastric nerve block in inguinal hernia repair patients. This prospective, randomised trial was conducted in 50 ASA I and II male patients≥18 years of age. Patients were randomised into two groups to receive either pre-incisional ipsilateral ultrasound-guided ilioinguinal-iliohypogastric nerve block or medial transverse abdominis plane block, with 0.3ml/kg of 0.25% bupivacaine. Our primary objective was postoperative 24-hour analgesic consumption and secondary outcomes included pain scores, time to first request for rescue analgesic and side effects, if any, in the postoperative period. There was no significant difference in the total postoperative analgesic consumption [group I: 66.04mg; group II: 68.33mg (P value 0.908)]. Time to first request for rescue analgesic was delayed, though statistically non-significant (P value 0.326), following medial transverse abdominis plane block, with excellent pain relief seen in 58.3% patients as opposed to 45.8% patients in ilioinguinal-iliohypogastric nerve block group. Medial transverse abdominis plane block being a novel, simple and easily performed procedure can serve as an useful alternative to ilioinguinal-iliohypogastric nerve block for providing postoperative pain relief in inguinal hernia repair patients.

Full Text Available Patological disorders within oral mucosa (so called mucositis are the most common stomatological complications among chemotherapy treated leukemic patients scheduled for bone marrow transplantation. Early diagnosis of such oral disorders leads to numerous side effects, decreasing quality of life and systemic complications is required. Furthermore, most patients require analgesic treatment, very often using narcotic pain medications. Presently the largest role of prevention and treatment of mucositis is preventative dentistry along with maintaining strict oral hygiene. This course of action aims to reduce pain and prevention of infections. Investigation of novel non-invasive therapeutic methods that could improve treatment outcomes seems justified. Among the most promising methods, the Low-level Laser Therapy (LLLT treatment demonstrates many beneficial effects for patients suffering from chemotherapy complications. It promotes mucosal healing and helps improve patients' quality of life. These advantages may be a result of a LLLT anti-inflammatory and analgesic effect. LLLT also promotes tissue regeneration through chemical changes in cells (cell repair. In recent clinical studies conducted on a group of patients with oral mucositis, the significant acceleration of mentioned disorders regression was noted. Moreover, reduction of pain after application of LLLT was recorded. Discussed in the article LLLT is easily accessible for clinical practice . Mentioned arguments justify a wider use of such a tool in non-invasive treatment of acute oral cavity inflammation.

Prosopis chilensis is used locally in Sudan for inflammatory conditions of joints; however, literature lacks scientific evidence for anti-inflammatory effect of this plant. To evaluate anti-inflammatory and analgesic effects of prosopis chilenses. Edema inhibition percent (EI %) and hot plate method were used to evaluate anti-inflammatory and analgesic effects of Prosopis chilenses in Wistar albino rats. Anti-inflammatory and analgesic effects of Prosopis chilenses were compared to indomethacin and acetylsalicylic acid respectively. Ethanolic extract of prosopis chilensis at a dose of 200 and 100mg/kg body weight achieved peak EI% (EI% = 96.1%) and (EI% = 94.4%) three and four hours after oral dosing respectively. The maximum EI% for indomethacin was 97.0% and was recorded after 4 hours following oral administration of the drug at a dose of 5 mg/kg body weight. Prosopis chilensis extracts at doses of 100 and 200 mg/kg body weight significantly increased the rats' response time to hot plate compared to acetylsalicylic acid at a dose rate of 100mg/kg body weight (Pprosopis chilenses. Relevance of these effects to prosopis chilenses phy-to-constituents was discussed.

The analgesic potency of butorphanol 25 microg/kg bodyweight (BW) and levomethadone 100 microg/kg BW, administered together with detomidine 10 microg/kg BW, was measured in twelve Warmblood horses in a randomized, blinded cross-over study. Detomidine with saline 10 ml 0.9% was used as placebo. The nociceptive threshold was determined using a constant current and a pneumatic pressure model for somatic pair Detomidine alone and in combination with butorphanol or levomethadone caused a significant temporary increase (P detomidine alone to both test methods. No significant difference between butorphanol and levomethadone was registered. It is concluded that the addition of butorphanol or levomethadone to detomidine increases the nociceptive threshold to somatic pain and prolongs the analgesic effect of detomidine in the horse.

Morphine is a well-characterized and effective analgesic commonly used to provide pain relief to patients suffering from both acute and chronic pain conditions. Despite its widespread use and effectiveness, one of the major drawbacks of morphine is its relatively short half-life of approximately 4 h. This short half-life often necessitates multiple administrations of the drug each day, which may contribute to both dependence and tolerance to morphine. Here, we tested the analgesic properties ...

Chronic Nonbacterial Prostatitis (CNBP) is a condition that frequently causes long-term pain and a significant decrease in the quality of life. The present study aimed to examine the analgesic effects of oligonol, acupuncture, quantum light therapy and their combinations on estrogen-induced CNBP in rats. This experimental study was conducted in Edirne, Turkey, using a simple randomized allocation. A total of 90 adult male Wistar rats were randomized into 9 groups of 10 rats each: Group I, control; Group II, CNBP, Group III, oligonol only, Group IV, acupuncture only; Group V, quantum only; Group VI, oligonol + quantum; Group VII, acupuncture + oligonol; Group VIII, quantum + acupuncture; Group IX, acupuncture + quantum + oligonol. Oligonol treatment was given at a dose of 60 mg/day for 6 weeks. Conceptual vessels (CV) 3 and 4, and bilaterally urinary bladder (Bl) 32 and 34 points were targeted with 1-hour acupuncture stimulation. The quantum light therapy was applied in 5-minute sessions for 6 weeks (3-times/a week). For pain measurements, mechanical pressure was applied to a point 2 cm distal to the root of the tail to elicit pain and consequent parameters (peak force, latency time of response and total length of measurement) were assessed. Analgesic effects were observed with all treatment regimens; however, the most prominent median analgesic effect was shown in the quantum light therapy in combination with acupuncture for estrogen-induced CNBP (PF1 = 663.9, PF2 = 403.4) (P = 0.012). Furthermore, we observed that monotherapy with quantum light showed a better analgesic efficacy as compared to oligonol and acupuncture monotherapies (PF1 = 1044.6, PF2 = 661.2) (P = 0.018, P = 0.008, P = 0.018; respectively). All treatment modalities showed a significant analgesic effect on CNBP in rats, being most prominent with the quantum light therapy.

The epidemic of prescription opioid overdose and mortality parallels the dispensing rates of prescription opioids, and the availability of increasingly potent opioid analgesics. The common assumption that more potent opioid analgesics are associated with higher rates of adverse outcomes has not been adequately substantiated. We compared the rate of serious adverse events among commonly prescribed opioid analgesics of varying potency. Serious adverse events (SAEs; defined as death, major medical effect, or hospitalization) resulting from exposure to tablets containing seven opioid analgesics (oxycodone, hydrocodone, morphine, hydromorphone, oxymorphone, tapentadol, and tramadol) captured by the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS ® ) System Poison Center Program were evaluated from 2010 through 2016. Rates of SAEs were adjusted for availability through outpatient dispensing data and regressed on morphine milligram equivalents (MME). There were 19,480 cases of SAE during the 7-year study period. Hydrocodone and oxycodone contributed to 77% of SAE cases. Comparing rates of outcome by relative potency, a hierarchy was observed with hydromorphone (8.02 SAEs/100 kg) and tapentadol (0.27 SAE/100 kg) as the highest and lowest rates, reflecting a 30-fold difference among individual opioid products. SAE rate and potency were related linearly-SAEs increased 2.04 per 100 kg drug dispensed for each 1-unit rise in MME (p = 0.004). Linear regression of SAE/100 kg drug dispensed and drug potency identified that MME comprised 96% of the variation observed. In contrast, potency did not explain variation seen using other study denominators (prescriptions dispensed, dosage units dispensed, and the number of individuals filling a prescription). Potency of a prescription opioid analgesic demonstrates a significant, highly positive linear relationship with exposures resulting in SAEs per 100 kg drug dispensed reported to poison centers

This study was undertaken to investigate the leaf part of the plant for analgesic and anti-inflammatory. The ethanol extract of Ficus iteophylla leaves (100, 200, and 400 mg kg(-1), i.p) was evaluated for analgesic and anti-inflammatory activities. The analgesic effect was studied using acetic acid-induced abdominal constriction and hot plate test in mice, while the anti-inflammatory effect was investigated using carrageenan induced paw oedema in rats. The ethanol extract at 100 mg kg(-1), 200 mg kg(-1), and 400 mg kg(-1) significantly (Pacetic acid induced writhes by 1.50 ± 0.43, 3.0 ± 0.82 and 1.0 ± 0.82 respectively. It also exhibited significantly (Pscreening of the plant extract revealed the presence of flavonoids, steroids, tannins and saponins while the effect of flavonoids, steroids and tannins on analgesic and inflammatory has been reported. The intraperitoneal median lethal dose (LD(50)) value of the extract was found to be 3807.8 mgkg(-1) body weights. The result obtained from this study shows that the extract of Ficus iteophylla contained phytochemical constituents with analgesic and anti-inflammatory activities, therefore the leaf part of the plant could be used in the management of pain and inflammatory conditions.

The purpose of this retrospective chart review was to document sedation and analgesic medications administered preoperotively, intraoperatively, and during postanesthesia care for children undergoing dental rehabilitation using general anesthesia (GA). Patient gender, age, procedure type performed, and ASA status were recorded from the medical charts of children undergoing GA for dental rehabilitation. The sedative and analgesic drugs administered pre-, intra-, and postoperatively were recorded. Statistical analysis included descriptive statistics and cross-tabulation. A sample of 115 patients with a mean age of 64 (+/-30) months was studied; 47% were females, and 71% were healthy. Over 80% of the patients were administered medications primarily during pre- and intraoperative phases, with fewer than 25% receiving medications postoperatively. Morphine and fentanyl were the most frequently administered agents intraoperatively. The procedure type, gender, and health status were not statistically associated with the number of agents administered. Younger patients, however, were statistically more likely to receive additional analgesic medications. Our study suggests that a minority of patients have postoperative discomfort in the postanesthesia care unit; mild to moderate analgesics were administered during intraoperative phases of dental rehabilitation.

Recent advances in neonatal intensive care include and are partly attributable to growing attention for comfort and pain control in the term and preterm infant requiring intensive care.Limitation of painful procedures is certainly possible, but most critically ill infants require unavoidable painful or stressful procedures such as intubation, mechanical ventilation, or catheterization.Many analgesics (opioids and nonsteroidal anti-inflammatory drugs)and sedatives (benzodiazepines and other anesthetic agents) are available but their use varies considerably among units. This review summarizes current experimental knowledge on the effects of sedative and analgesic drugs on brain development and reviews clinical evidence that speaks for or against the use of common analgesic and sedative drugs in the NICU but avoids any discussion of anesthesia during surgery. Risk/benefit ratios of intermittent boluses or continuous infusions for the commonly used sedative and analgesic agents are discussed in the light of clinical and experimental studies. The limitations of extrapolating experimental results from animals to humans must be considered while making practical recommendations based on the currently available evidence.

To evaluate the different fractions of dried leaves of Ficus religiosa Linn for analgesic and anti-inflammatory activity using different models of pain and inflammation The analgesic activity of F. religiosa carried out using acetic acid-induced writhing in mice and tail flick test in rats. The anti-inflammatory activity was evaluated using carrageenan-induced rat paw edema and cotton pellet-granuloma formation in rats. Five different fractions (FRI, FRII, FRIII, FRIV and FRV) of F. religiosa at the dose level of 20 and 40 mg/kg, p.o were tested. The fraction FRI (40 mg/kg, p.o.) and FRIII (40 mg/kg, p.o) were found to be more effective (Pacetic acid induced writhing compared to the other fractions. FRI (20 mg/kg, p.o.) and FRIII (20 mg/kg, p.o.) were also found to be more effective in increasing latency period in tail flick method. Out of five different fractions of F. religiosa leaves tested, FRI and FRIII possess potent analgesic and anti-inflammatory activities against different models of inflammation and pain.

Evidence from other countries has suggested that many controlled drugs are also offered online, even though it is illegal to sell these drugs without a license. To evaluate the current contents related to the supply and demand of sedatives and analgesic drugs available online in Thailand, with a particular focus on Facebook. A team of reviewers manually searched for data by entering keywords related to analgesic drugs and sedatives. The contents of the website were screened for supply and demand-related information. A total of 5,352 websites were found publicly available. The number of websites and Facebook pages containing the information potentially related to the supply and demand of analgesic drugs and sedatives was limited. Nine websites sold sedatives, and six websites sold analgesics directly. Fourteen Facebook pages were found, including 7 sedative pages and 7 analgesic pages. Within one year, the three remaining active pages multiplied in the number of followers by three- to nine-fold. The most popular Facebook page had over 2,900 followers. Both the internet and social media contain sites and pages where sedatives and analgesics are illegally advertised. These websites are searchable through common search engines. Although the number of websites is limited, the number of followers on these Facebook pages does suggest a growing number of people who are interested in such pages. Our study emphasized the importance of monitoring and developing potential plans relative to the online marketing of prescription drugs in Thailand.

Local analgesic effect of tramadol is not mediated by opioid receptors in early postoperative pain in rats

Directory of Open Access Journals (Sweden)

Angela Maria Sousa

2015-06-01

Full Text Available BACKGROUND AND OBJECTIVES: Tramadol is known as a central acting analgesic drug, used for the treatment of moderate to severe pain. Local analgesic effect has been demonstrated, in part due to local anesthetic-like effect, but other mechanisms remain unclear. The role of peripheral opioid receptors in the local analgesic effect is not known. In this study, we examined role of peripheral opioid receptors in the local analgesic effect of tramadol in the plantar incision model. METHODS: Young male Wistar rats were divided into seven groups: control, intraplantar tramadol, intravenous tramadol, intravenous naloxone-intraplantar tramadol, intraplantar naloxone-intraplantar tramadol, intravenous naloxone-intravenous tramadol, and intravenous naloxone. After receiving the assigned drugs (tramadol 5 mg, naloxone 200 µg or 0.9% NaCl, rats were submitted to plantar incision, and withdrawal thresholds after mechanical stimuli with von Frey filaments were assessed at baseline, 10, 15, 30, 45 and 60 min after incision. RESULTS: Plantar incision led to marked mechanical hyperalgesia during the whole period of observation in the control group, no mechanical hyperalgesia were observed in intraplantar tramadol group, intraplantar naloxone-intraplantar tramadol group and intravenous naloxone-intraplantar tramadol. In the intravenous tramadol group a late increase in withdrawal thresholds (after 45 min was observed, the intravenous naloxone-intravenous tramadol group and intravenous naloxone remained hyperalgesic during the whole period. CONCLUSIONS: Tramadol presented an early local analgesic effect decreasing mechanical hyperalgesia induced by plantar incision. This analgesic effect was not mediated by peripheral opioid receptors.

Analgesic intolerance (AI) appears in approximately 1 % of the general population. The triad of bronchial asthma, nasal polyposis, and analgesic intolerance is called analgesic-induced asthma (AIA). These patients are frequently referred to adult allergy clinics for preoperative evaluation for possible analgesic cross reactivity and intolerance to anesthetic agents. To determine allergic problems related to anesthesia and postoperative pain management in AI patients with and without asthma. The medical records of 45 patients who had been diagnosed with AI between January 1991 and December 2002 in the adult allergy unit and who underwent surgery in the same hospital in the last 4 years were retrospectively analyzed. The mean age of the patients was 44.4 13.4 years and 30 (66.6 %) were female. Thirty-six (80 %) had AIA, 34 (75.6 %) had persistent allergic rhinitis and 21 (46.7 %) had nasal polyps. Fifty-one surgical procedures were performed in 45 patients, in whom ear, nose and throat surgery was the main procedure (64.7 %). Anesthesia was induced with propofol, fentanyl, and vecuronium and was maintained by sevoflurane or isoflurane. Fentanyl was used for early postoperative pain relief. No complications appeared in relation to anesthesia or early pain management except in a 44-year-old AIA woman who had a reaction in the postoperative period after receiving an inappropriate analgesic. None of the patients had anesthesia-related allergic problems. Atropine and diazepam in the premedication, propofol and fentanyl during induction, muscle relaxation facilitation by vecuronium, and sevoflurane or isoflurane for maintenance seem to be a safe general anesthetic choice for analgesic intolerant patients with and without asthma.

To assess the immediate analgesic effect of wrist-ankle acupuncture on acute lumbago and the relationship between the analgesic effect and the expectation of patients. A randomized, single-blind, sham-controlled trial was designed. Sixty cases of acute lumbago were randomly divided into two groups, 30 cases in each one. In observation group, wrist-ankle acupuncture was adopted to the Lower 5 and Lower 6 bilaterally, no requirement of Deqi (arrival of qi). In control group, sham acupuncture was adopted. The treatment was applied once in either group, with the needles retained for 30 min. The Short-form McGill Pain Questionnaire (SF-MPQ) and the Modified-Modified Schober (MMS) test were used to assess the motion related pain and the situation of spinal flexion in 3 min before treatment and 5 min, 10 min, 15 min, during treatment and 30 min (needle removed), respectively. The Expectation and Treatment Credibility Scale (ETCS) was applied to analyze the relationship between the expectation of patients and the analgesic effect. The adverse reaction was recorded. There were no statistically significant differences in SF-MPQ, MMS and ETCS before treatment between two groups (all P>0.05). In 5 min after needles insertion, the scores of the items in SF-MPQ in observation group were lower than those in control group (P0.05). No adverse reaction was reported. Wrist-ankle acupuncture can reduce acute lumbago immediately and significantly. The higher the expectation on the analgesic effect of wrist-ankle acupuncture the patients have, the better the analgesic effect will be. This therapy is highly safe in the treatment.

Full Text Available This work aimed to evaluate the analgesic efficacy of intra-articular injection of magnesium sulphate (4% compared with equivalent volume of bupivacaine (0.5% after outpatient knee arthroscopic meniscectomy. Forty patients were randomly assigned to two groups. Group M (n = 20 received intra-articular magnesium sulphate 4%, group B (n = 20 received bupivacaine (0.5%. Analgesic effect was evaluated by analgesic duration, and by measuring pain intensity at 1, 2, 4, 6, 12, 24 h both at rest and on knee movement to 90°. The primary outcome variable was pain intensity on the VAS at 1, 2, 4, 6, 12, 24 h post arthroscopy at rest and on movement (flexion of knee to 90°, although the magnesium group had lower time weighted averages (TWAs at rest and on movement, these TWAs were not statistically significant. The median duration of postoperative analgesia was significantly longer in the patients treated with magnesium sulphate (528 min than in the bupivacaine group (317 min (p < 0.0001, with less number of patients needing supplementary analgesia in magnesium group (8/20 than those of the bupivacaine group (16/20 (p < 0.022. Also analgesic consumption was significantly lower in the magnesium sulphate group (p < 0.002. We concluded that the use of magnesium sulphate is rational and effective in reducing pain, and is more physiological and shortens convalescence after outpatient arthroscopic meniscectomy, however our hypotheses that analgesic efficacy of intra-articular isotonic magnesium sulphate would be superior to intra-articular local anaesthetic cannot be supported with this study.

Effective atomic numbers for photon energy absorption ZPEA,eff, photon interaction ZPI,eff and for electron density Nel, have been calculated by a direct method in the photon-energy region from 1 keV to 20 MeV for narcotic drugs, such as Heroin (H), Cocaine (CO), Caffeine (CA), Tetrahydrocannabinol (THC), Cannabinol (CBD), Tetrahydrocannabivarin (THCV). The ZPEA,eff, ZPI,eff and Nel values have been found to change with energy and composition of the narcotic drugs. The energy dependence ZPEA,eff, ZPI,eff and Nel is shown graphically. The maximum difference between the values of ZPEA,eff, and ZPI,eff occurs at 30 keV and the significant difference of 2 to 33% for the energy region 5-100 keV for all drugs. The reason for these differences is discussed.

Full Text Available Shells are by-products of oil production from Camellia oleifera which have not been harnessed effectively. The purpose of this research is to isolate flavonoid from shells of Camellia oleifera and evaluate its anti-inflammatory and analgesic effects. The flavonoid was identified as bimolecular kaempferol structure by UV, MS, 1H NMR and 13C NMR spectra, which is a new biflavonoid and first found in Camellia oleifera. It showed dose-dependent anti-inflammatory activity by carrageenin-induced paw oedema in rats and croton oil induced ear inflammation in mice, and analgesic activity by hot plate test and acetic acid induced writhing. The mechanism of anti-inflammation of biflavonoid is related to both bradykinin and prostaglandins synthesis inhibition. The biflavonoid showed both central and peripheral analgesic effects different from aspirin, inhibition of the synthesis or action of prostaglandins may contribute to analgesic effect of biflavonoid. The biflavonoid significantly decreased malonaldehyde (MDA and increased superoxidase dismutase (SOD and Glutathione peroxidase (GSH-Px activity in serum (p < 0.01, revealed strong free radical scavenging activity in vivo. It indicates the biflavonoid can control inflammation and pain by eliminating free radical so as to inhibit the mediators and decrease the prostaglandins. The biflavonoid can be used as a prospective medicine for inflammation and pain.

Vocal local (VL) is a non-pharmacological pain management technique for gynecological procedures. In Africa, it is usually used in combination with pharmacological analgesics. However, analgesics are associated with side-effects, and can be costly and subject to frequent stock-outs, particularly in remote rural settings. We compared the effectiveness of VL + local anesthesia + analgesics (the standard approach), versus VL + local anesthesia without analgesics, on pain and satisfaction levels for women undergoing tubal ligations in rural Kenya. We conducted a site-randomised non-inferiority trial of 884 women receiving TLs from 40 Marie Stopes mobile outreach sites in Kisii and Machakos Districts. Twenty sites provided VL + local anesthesia + analgesics (control), while 20 offered VL + local anesthesia without additional analgesics (intervention). Pain was measured using a validated 11-point Numeric Rating Scale; satisfaction was measured using 11-point scales. A total of 461 women underwent tubal ligations with VL + local anesthesia, while 423 received tubal ligations with VL + local anesthesia + analgesics. The majority were aged ≥30 years (78%), and had >3 children (99%). In a multivariate analysis, pain during the procedure was not significantly different between the two groups. The pain score after the procedure was significantly lower in the intervention group versus the control group (by 0.40 points; p = 0.041). Satisfaction scores were equally high in both groups; 96% would recommend the procedure to a friend. VL + local anesthesia is as effective as VL + local anesthesia + analgesics for pain management during tubal ligation in rural Kenya. Avoiding analgesics is associated with numerous benefits including cost savings and fewer issues related to the maintenance, procurement and monitoring of restricted opioid drugs, particularly in remote low-resource settings where these systems are weak.

Sports drug testing laboratories are required to detect several classes of compounds that are prohibited at all times, which include anabolic agents, peptide hormones, growth factors, beta-2 agonists, hormones and metabolic modulators, and diuretics/masking agents. Other classes of compounds such as stimulants, narcotics, cannabinoids, and glucocorticoids are also prohibited, but only when an athlete is in competition. A single class of compounds can contain a large number of prohibited substances and all of the compounds should be detected by the testing procedure. Since there are almost 70 stimulants on the prohibited list it can be a challenge to develop a single screening method that will optimally detect all the compounds. We describe a combined liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-mass spectrometry (GC-MS) testing method for detection of all the stimulants and narcotics on the World Anti-Doping Agency prohibited list. Urine for LC-MS/MS testing does not require sample pretreatment and is a direct dilute and shoot method. Urine samples for the GC-MS method require a liquid-liquid extraction followed by derivatization with trifluoroacetic anhydride.

Neuropathic pain caused by nerve injury is debilitating and difficult to treat. Current systemic pharmacological therapeutics for neuropathic pain produce limited pain relief and have undesirable side effects, while current local anesthetics tend to nonspecifically block both sensory and motor functions. Calcitonin gene related peptide (CGRP), a neuropeptide released from sensory nerve endings, appears to play a significant role in chronic neuropathic pain. In this study, an analgesic microneedle (AMN) patch was developed using dissolvable microneedles to transdermally deliver selective CGRP antagonist peptide in a painless manner for the treatment of localized neuropathic pain. Local analgesic effects were evaluated in rats by testing behavioral pain sensitivity in response to thermal and mechanical stimuli using neuropathic pain models such as spared-nerve injury and diabetic neuropathy pain, as well as neurogenic inflammatory pain model induced by ultraviolet B (UVB) radiation. Unlike several conventional therapies, the AMN patches produced effective analgesia on neuropathic pain without disturbing the normal nociception and motor function of the rat, resulting from the high specificity of the delivered peptide against CGRP receptors. The AMN patches did not cause skin irritation or systemic side effects. These results demonstrate that dissolvable microneedle patches delivering CGRP antagonist peptide provide an effective, safe, and simple approach to mitigate neuropathic pain with significant advantages over current treatments.

Full Text Available Ononitol monohydrate (OM was isolated from Cassia tora L. leaves. The anti-inflammatory and analgesic activities of OM have been examined in male Wistar rats and mice. The efficacy of OM against inflammation was studied by using carrageenan-induced paw oedema, croton oil-induced ear oedema, acetic acid-induced vascular permeability, cotton pellet-induced granuloma and adjuvant-induced arthritis. The analgesic activity of OM was assessed using the acetic acid-induced abdominal constriction response, formalin-induced paw licking response and the hot-plate test. In acute type inflammation models, maximum inhibitions of 50.69 and 61.06% (P < .05 were noted with 20 mg/kg of OM in carrageenan-induced hind paw oedema and croton oil-induced ear oedema, respectively. Treatment of OM (20 mg/kg meaningfully (P < .05 reduced the granuloma tissue formation by cotton pellet study at a rate of 36.25%. OM (20 mg/kg inhibited 53.64% of paw thickness in adjuvant-induced arthritis model. OM has also been produced significant (P < .05 analgesic activity in acetic acid-induced abdominal constriction response, formalin-induced paw licking response and in hot-plate test suggesting its peripheral and central analgesic potential. The outcomes of the present study proposed that OM influenced on the anti-inflammatory and analgesic activities.

Full Text Available Aim: The research was carried out to investigate the analgesic and anti-inflammatory effects of ethanol extract of Desmodium pauciflorum, Mangifera indica and Andrographis paniculata leaves. Materials and Methods: In order to assess the analgesic and anti-inflammatory effects acetic acid induced writhing response model and carrageenan induced paw edema model were used in Swiss albino mice and Wistar albino rats, respectively. In both cases, leaves extract were administered (2gm/kg body weight and the obtained effects were compared with commercially available analgesic and anti-inflammatory drug Dclofenac sodium (40mg/kg body weight. Distilled water (2ml/kg body weight was used as a control for the study. Results: In analgesic bioassay, oral administration of the ethanol extract of leaves were significantly (p<0.01 reduced the writhing response. The efficacy of leaves extract were almost 35% in Desmodium pauciflorum, 56% in Mangifera indica and 34% in Andrographis paniculata which is found comparable to the effect of standard analgesic drug diclofenac sodium (76%. Leaves extract reduced paw edema in variable percentages but they did not show any significant difference among the leaves. Conclusion: We recommend further research on these plant leaves for possible isolation and characterization of the various active chemical substances which has the toxic and medicinal values.

Jia-Yuan-Qing pill (JYQP) composed of Porcellio laevis Latreille, Corydalis Rhizoma and Radix Cynanchi Paniculati at a ratio of 9:7:7 has been found to be an effective analgesic agent. The present study aimed to evaluate the safety, addictive potential and anti-cancer pain activity of JYQP in a rat model. During the 6-month chronic toxicity test, no significant changes in general behavior, defecation, postural abnormalities, dietary or water intake or blood biochemical parameters were observed in male and female rats. Although a high dose of JYQP (5 g/kg) caused swelling of the liver, spleen and kidney in male and female rats, no pathological changes were observed in all organs examined via hematoxylin and eosin staining. The analgesic effect of JYQP on bone cancer pain was successfully confirmed in a rat model of Walker 256 cell-induced bone cancer. In contrast to morphine, in a physical dependence test, JYQP produced no withdrawal symptoms following chronic administration. The data from this study provide experimental evidence supporting the clinical use of JYQP as an effective, safe and non-addictive agent for the treatment of bone cancer pain.

Full Text Available Qian Yang, Chuang Zhao, Jun Zhao, Yong Ye Department of Pharmaceutical Engineering, School of Chemistry and Chemical Engineering, South China University of Technology, Guangzhou, People’s Republic of China Abstract: Cobra neurotoxin (CNT, a peptide isolated from snake venom of Naja naja atra, shows central analgesic effects in our previous research. In order to help CNT pass through blood–brain barrier (BBB and improve its central analgesic effects, a new kind of CNT nanocapsules were prepared by double emulsification with soybean lecithin and cholesterol as the shell, and pheophorbide as the photosensitizer added to make it photoresponsive. The analgesic effects were evaluated by hot plate test and acetic acid-induced writhing in mice. The CNT nanocapsules had an average particle size of 229.55 nm, zeta potential of -53.00 mV, encapsulation efficiency of 84.81% and drug loading of 2.98%, when the pheophorbide content was 1% of lecithin weight. Pheophorbide was mainly distributed in outer layer of the CNT nanocapsules and increased the release of the CNT nanocapsules after 650 nm illumination. The central analgesic effects were improved after intraperitoneal injection of CNT at 25 and 50 µg·kg-1 under 650 nm irradiation for 30 min in the nasal cavity. Activation of pheophorbide by red light generated reactive oxygen species which opened the nanocapsules and BBB and helped the CNT enter the brain. This research provides a new drug delivery for treatment of central pain.

2014-09-01

Full Text Available Background and objectives: Esmolol is known to have no analgesic activity and no anaesthetic properties; however, it could potentiate the reduction in anaesthetic requirements and reduce postoperative analgesic use. The objective of this study is to evaluate the effect of intravenous esmolol infusion on intraoperative and postoperative analgesic consumptions as well as its effect on depth of anaesthesia. Methods: This randomized-controlled double blind study was conducted in a tertiary care hospital between March and June 2010. Sixty patients undergoing septorhinoplasty were randomized into two groups. History of allergy to drugs used in the study, ischaemic heart disease, heart block, bronchial asthma, hepatic or renal dysfunction, obesity and a history of chronic use of analgesic or β-blockers were considered cause for exclusion from the study. Thirty patients received esmolol and remifentanil (esmolol group and 30 patients received normal saline and remifentanil (control group as an intravenous infusion during the procedure. Mean arterial pressure, heart rate, and bispectral index values were recorded every 10min. Total remifentanil consumption, visual analogue scale scores, time to first analgesia and total postoperative morphine consumption were recorded. Results: The total remifentanil consumption, visual analogue scale scores at 0, 20 and 60 min, total morphine consumption, time to first analgesia and the number of patients who needed an intravenous morphine were lower in the esmolol group. Conclusions: Intravenous infusion of esmolol reduced the intraoperative and postoperative analgesic consumption, reduced visual analogue scale scores in the early postoperative period and prolonged the time to first analgesia; however it did not influence the depth of anaesthesia.

Pain is the major concern of patients attending dental clinics, and satisfactory pain relief has always been difficult to achieve. Since the pathophysiology of pain is a complex, central and peripheral nervous system process, combined analgesic regimens with different mechanisms of action as a multimodal approach are becoming popular among the clinicians and dentists. The aim of the present study was to evaluate the analgesic and anti-inflammatory activity of ibuprofen and tramadol when used alone or in combination in animal models of pain and inflammation. The animals were divided into six groups with six animals in each group. Analgesic activity was assessed by hot plate method in rats and by acetic acid-induced writhing test in mice. Paw edema model in rats after induction with 0.1 mL of 1% carrageenan was used to assess the anti-inflammatory activity. Analysis of variance followed by Tukey's honestly significant difference post hoc test was used for statistical analysis. Combined use of tramadol and ibuprofen provided enhanced analgesic and anti-inflammatory effects in animal models of pain and inflammation.

The objectives of this study were to assess the efficacy of preemptive oral administration of single dose of non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen on the local anesthetic success in adults with irreversible pulpitis and to find the possible covariates that could predict treatment effect. A systematic search using electronic databases up to March 2015 was conducted. Odds ratio (OR) and 95% confidence intervals (CIs) were estimated using random and fixed-effect inverse variance method. Subgroup and meta-regression analyses were conducted to assess the potential source of heterogeneity. Results showed that preemptive analgesics are more effective than placebo in increasing anesthetic success (OR = 0.30, CI% 0.24-0.39, p = 0.000) [Q = 55.860 (p = 0.001)]. In the subgroup analysis, administration of NSAIDs as monotherapy, ibuprofen as mono- vs. combination therapy, oxicam type drugs as monotherapy, and acetaminophen as combination therapy were significantly more effective in increasing anesthetic success OR = 0.25, CI% 0.16-0.38, p = 0.00, Q = 40.539 (p = 0.003); OR = 0.44, CI% 0.26-0.75, p = 0.00, Q = 12.833 (p = 0.011); OR = 0.48, CI% 0.30-0.74, p = 0.002, Q = 15.898 (p = 0.14); OR = 0.30, CI% 0.16-0.38, p = 0.001, Q = 7.506 (p = 0.02); OR = 0.10, CI% 0.16 0.38, p = 0.001, Q = 5.075 (p = 0.07), respectively. However, there was no significant difference in increasing anesthetic success between treatment and placebo arms when acetaminophen was administrated alone. In meta-regression analysis, an association between different types of NSAIDs (indomethacin, diclofenac potassium, and oxicam-type drugs) and articaine with treatment effect was observed. The administration of preemptive analgesics can induce superior intraoperative analgesia for patients with irreversible pulpitis. However, strategies such as co-administration of certain types of analgesics and anesthetic solution might be predictors

Full Text Available Diffuse noxious inhibitory control (DNIC is described as one possible mechanism of acupuncture analgesia. This study investigated the analgesic effect of acupuncture without stimulation compared to nonpenetrating sham acupuncture (NPSA and cold-pressor-induced DNIC. Forty-five subjects received each of the three interventions in a randomized order. The analgesic effect was measured using pressure algometry at the second toe before and after each of the interventions. Pressure pain detection threshold (PPDT rose from 299 kPa (SD 112 kPa to 364 kPa (SD 144, 353 kPa (SD 135, and 467 kPa (SD 168 after acupuncture, NPSA, and DNIC test, respectively. There was no statistically significant difference between acupuncture and NPSA at any time, but a significantly higher increase of PPDT in the DNIC test compared to acupuncture and NPSA. PPDT decreased after the DNIC test, whereas it remained stable after acupuncture and NPSA. Acupuncture needling at low pain stimulus intensity showed a small analgesic effect which did not significantly differ from placebo response and was significantly less than a DNIC-like effect of a painful noninvasive stimulus.

Bachhuber, Marcus A.; Saloner, Brendan; Cunningham, Chinazo O.; Barry, Colleen L.

2015-01-01

IMPORTANCE Opioid analgesic overdose mortality continues to rise in the United States, driven by increases in prescribing for chronic pain. Because chronic pain is a major indication for medical cannabis, laws that establish access to medical cannabis may change overdose mortality related to opioid analgesics in states that have enacted them. OBJECTIVE To determine the association between the presence of state medical cannabis laws and opioid analgesic overdose mortality. DESIGN, SETTING, AND PARTICIPANTS A time-series analysis was conducted of medical cannabis laws and state-level death certificate data in the United States from 1999 to 2010; all 50 states were included. EXPOSURES Presence of a law establishing a medical cannabis program in the state. MAIN OUTCOMES AND MEASURES Age-adjusted opioid analgesic overdose death rate per 100 000 population in each state. Regression models were developed including state and year fixed effects, the presence of 3 different policies regarding opioid analgesics, and the state-specific unemployment rate. RESULTS Three states (California, Oregon, and Washington) had medical cannabis laws effective prior to 1999. Ten states (Alaska, Colorado, Hawaii, Maine, Michigan, Montana, Nevada, New Mexico, Rhode Island, and Vermont) enacted medical cannabis laws between 1999 and 2010. States with medical cannabis laws had a 24.8% lower mean annual opioid overdose mortality rate (95% CI, −37.5% to −9.5%; P = .003) compared with states without medical cannabis laws. Examination of the association between medical cannabis laws and opioid analgesic overdose mortality in each year after implementation of the law showed that such laws were associated with a lower rate of overdose mortality that generally strengthened over time: year 1 (−19.9%; 95% CI, −30.6% to −7.7%; P = .002), year 2 (−25.2%; 95% CI, −40.6% to −5.9%; P = .01), year 3 (−23.6%; 95% CI, −41.1% to −1.0%; P = .04), year 4 (−20.2%; 95% CI, −33.6% to −4

In Vivo and In Vitro Elution of Analgesics from Multilayered Poly(D,L-lactide-co-glycolide Nanofibers Incorporated Ureteral Stents

Full Text Available We develop novel analgesic-eluting nanofiber-incorporated ureteral stents that offer sustained release of lidocaine and ketorolac for local drug delivery. Lidocaine and poly(D,L-lactide-co-glycolide (PLGA were dissolved in hexafluoroisopropanol and were electrospun into nonwoven nanofibers onto the surface of ureteral stents. This was followed by electrospinning of another layer of PLGA nanofibers containing ketorolac. Electrospun drug-loaded nanofibers were then characterized using scanning electron microscopy, Fourier transform infrared spectroscopy, and water contact angle analysis. In addition, the elution behavior characteristics of the analgesics, both in vivo and in vitro, from the nanofiber-incorporated stents were evaluated. Experimental results indicate that the analgesic-eluting ureteral stents could liberate high strengths of analgesics in vitro and in vivo for at least 50 and 30 days, respectively. The analgesic-eluting nanofiber-incorporated ureteral stents are potentially applicable for alleviating the discomfort associated with stent implant.

Full Text Available Jennifer Hansen, Ravi D Shah, Hubert A Benzon Department of Pediatric Anesthesiology, Ann and Robert H. Lurie Children's Hospital of Chicago, Northwestern University Feinberg School of Medicine, Chicago, IL, USA Abstract: Tonsillectomy is associated with significant pain and postoperative pain control is often unsatisfactory. We discuss the various strategies that have been investigated to control pain following tonsillectomy. Codeine is a weak analgesic frequently used in children for the treatment of mild-to-moderate pain, however, due to adverse events related to its metabolism, it has been contraindicated for postoperative pain in children since 2013. Intravenous morphine is frequently used for moderate-to-severe pain in children, however, its active metabolite can lead to respiratory depressant and other undesirable side effects. Hydromorphone is a commonly used alternative that has been studied infrequently. Alternatives to narcotic pain strategies have also been studied. Nonsteroidal anti-inflammatory drugs (NSAIDs are effective as analgesics, yet many practitioners avoid their use given the concern for postoperative bleeding. Intraoperative acetaminophen has been shown to improve postoperative pain and decrease recovery room time. Dexamethasone has been shown to improve postoperative pain, vomiting, and decrease airway swelling, and seems to be effective for use during tonsillectomy surgery. Ketamine has been shown to decrease analgesic requirements without adverse affects of hallucinations. Direct injection of local anesthetic into the tonsillar bed has been shown to be effective in improving pain control, however, there is concern that local anesthetic could be erroneously injected into the carotid artery and lead to devastating consequences. Optimal pain control regimens following pediatric tonsillectomy continue to be a challenge for both anesthesiologists and otorhinolaryngologists. Opioids are the most commonly used but are

In the review article by Kopsky and Stahl, four critical barriers in the process of research and development of topical analgesics were indicated. The active pharmaceutical ingredient (API and the formulation are among the major challenges. The road to the development of such drugs passes through preclinical studies. These studies, if planned correctly, should serve as guidance for choosing the right API and formulation. Although rodent models for pain continue to provide valuable data on the mechanisms driving pain, their use in developing topical and localized treatment approaches is limited for technical (intraplate injection area is small as well as mechanical reasons (non-similarity to human skin and innervation. It has been previously shown that pigs are comparable to humans in ways that make them a better choice for evaluating topical and local analgesics. The aim of this study was to summarize several experiments that used pigs for testing postoperative pain in an incisional pain model (skin incision [SI] and skin and muscle incision [SMI]. At the end of the surgery, the animals were treated with different doses of bupivacaine solution (Marcaine®, bupivacaine liposomal formulation (Exparel® or ropivacaine solution (Naropin.

The objectives were to report the baseline (prior to quality improvement interventions) patient and visit characteristics and analgesic management practices for each site participating in an emergency department (ED) sickle cell learning collaborative. A prospective, multisite longitudinal cohort study in the context of a learning-collaborative model was performed in three midwestern EDs. Each site formed a multidisciplinary team charged with improving analgesic management for patients with sickle cell disease (SCD). Each team developed a nurse-initiated analgesic protocol for SCD patients (implemented after a baseline data collection period of 3.5 months at one site and 10 months at the other two sites). All sites prospectively enrolled adults with an acute pain crisis and SCD. All medical records for patients meeting study criteria were reviewed. Demographic, health services, and analgesic management data were abstracted, including ED visit frequency data, ED disposition, arrival and discharge pain score, and name and route of initial analgesic administered. Ten interviews per quarter per site were conducted with patients within 14 days of their ED discharge, and subjects were queried about the highest level of pain acceptable at discharge. The primary outcome variable was the time to initial analgesic administration. Variable data were described as means and standard deviations (SDs) or medians and interquartile ranges (IQR) for nonnormal data. A total of 155 patients met study criteria (median age = 32 years, IQR = 24-40 years) with a total of 701 ED visits. Eighty-six interviews were conducted. Most patients (71.6%) had between one and three visits to the ED during the study period. However, after removing Site 3 from the analysis because of the short data enrollment period (3.5 months), which influenced the mean number of visits for the entire cohort, 52% of patients had between one and three ED visits over 10 months, 21% had four to nine visits, and 27% had

Grewia asiatica Linn. (Family: Tiliaceae), called Phalsa in Hindi is an Indian medicinal plant used for a variety of therapeutic and nutritional uses. The root bark of the plant is traditionally used in rheumatism (painful chronic inflammatory condition). The present study demonstrates the analgesic and anti-inflammatory activity of root bark of G. asiatica in rodents. The methanolic extract of Grewia asiatica (MEGA) and aqueous extract of Grewia asiatica (AEGA) of the bark were prepared and subjected to phytochemical tests and pharmacological screening for analgesic and anti-inflammatory effect in rodents. Analgesic effect was studied using acetic acid-induced writhing in mice and hot plate analgesia in rats while anti-inflammatory activity was investigated using carrageenan-induced paw oedema in rats. The MEGA or AEGA was administered orally in doses of 200 and 400 mg/kg/day of body weight. Data were analysed by one-way analysis of variance followed by Dunnett's test. The extracts showed a significant inhibition of writhing response and increase in hot plate reaction time and also caused a decrease in paw oedema. The effects were comparable with the standard drugs used. The present study indicates that root bark of G. asiatica exhibits peripheral and central analgesic effect and anti-inflammatory activity, which may be attributed to the various phytochemicals present in root bark of G. asiatica.

Full Text Available Background. Inflammation and pain are closely related to humans’ and animals’ health. Resveratrol (RSV is a natural compound with various biological activities. The current study is aimed to evaluate the analgesic and anti-inflammatory activities of RSV in vivo. Materials and Methods. The analgesic effects were assessed by the acetic acid-induced writhing and hot plate tests. The anti-inflammatory effects were determined using the xylene-induced mouse ear oedema, the acetic acid-induced rat pleurisy, and carrageenan-induced rat synovitis tests, respectively. Results. The analgesic results showed that RSV could significantly inhibit the number of writhes and improve the time and pain threshold of mice standing on hot plate. The anti-inflammatory results showed that RSV could inhibit the ear oedema of mice. In acetic acid-induced pleurisy test, RSV could significantly inhibit the WBC and pleurisy exudates, could decrease the production of NO, and elevate the activity of SOD in serum. In carrageenan-induced synovitis test, RSV could reduce the content of MDA and elevate the T-SOD activity in serum; RSV could inhibit the expressions of TP, PGE2, NO, and MDA. Conclusion. Shortly, these results indicated that RSV had potent analgesic and anti-inflammatory activities and could be a potential new drug candidate for the treatment of inflammation and pain.

Full Text Available Ageratina glabrata (Kunth R.M. King & H. Rob., Asteraceae (syn. Eupatorium glabratum Kunth is widely distributed throughout Mexico and popularly known as "chamizo blanco" and "hierba del golpe" for its traditional use as external analgesic remedy. Though glabrata species has been chemically studied, there are no experimentally asserted reports about possible analgesic effects which can be inferred from its genus Ageratina. To fill the gap, we evaluated A. glabrata extracts in an animal model of nociception exploiting thermal stimuli. NMR and mass analyses identified a new thymol derivative, 10-benzoiloxy-6,8,9-trihydroxy-thymol isobutyrate (1, which was computationally converted into a ring-closed structure to explain interaction with the COX-2 enzyme in a ligand-receptor docking study. The resulting docked pose is in line with reported crystal complexes of COX-2 with chromene ligands. Based on the present results of dichloromethane extracts from its dried leaves, it is safe to utter that the plant possesses analgesic effects in animal tests which are mediated through inhibition of COX-2 enzyme.

relieving distressing symptoms and managing the side effects of analgesics are essential in order to improve quality of life and functional capacity in chronic non-cancer pain patients. A quick, reliable and valid tool for assessing symptoms and side effects is needed in order to optimize treatment. We aimed to investigate the symptoms reported by chronic non-cancer pain patients after open-ended questioning vs. a systematic assessment using a list of symptoms, and to assess whether the patients could distinguish between the symptoms and the side effects induced by analgesics. patients treated with either opioids and/or adjuvant analgesics were asked to report their symptoms spontaneously, followed by a 41-item investigator-developed symptom checklist. A control group also filled in the checklist. a total of 62 patients and 64 controls participated in the study. The numbers of symptoms reported by the patients (9.9 ± 5.9) were significantly higher than those reported by the controls (3.2 ± 3.9) (Pside effects due to analgesics was: (1) Dry mouth (42%); (2) Sweating (34%); (3) Weight gain (29%); (4) Memory deficits (24%); (5) Fatigue (19%); and (6) Concentration deficits (19%). the number of symptoms reported using systematic assessment was eightfold higher than those reported voluntarily. Fatigue, cognitive dysfunction, dry mouth, sweating and weight gain were the most frequently reported. The patients reported the side effects of their analgesics to contribute substantially to the reported symptoms. 2010 The Acta Anaesthesiologica Scandinavica Foundation.

Highlights: ► New kyotorphin derivatives have antimicrobial properties against S. aureus. ► Atomic force microscopy show membrane disturbing effects of KTP–NH 2 and IbKTP–NH 2 . ► None of the KTP derivatives are hemolytic. ► The minimal peptidic sequence with antimicrobial activity is Tyr-Arg, if amidated. -- Abstract: Antimicrobial peptides (AMPs) are promising candidates as alternatives to conventional antibiotics for the treatment of resistant pathogens. In the last decades, new AMPs have been found from the cleavage of intact proteins with no antibacterial activity themselves. Bovine hemoglobin hydrolysis, for instance, results in AMPs and the minimal antimicrobial peptide sequence was defined as Tyr-Arg plus a positively charged amino acid residue. The Tyr-Arg dipeptide alone, known as kyotorphin (KTP), is an endogenous analgesic neuropeptide but has no antimicrobial activity itself. In previous studies new KTP derivatives combining C-terminal amidation and Ibuprofen (Ib) – KTP–NH 2 , IbKTP, IbKTP–NH 2 – were designed in order to improve KTP brain targeting. Those modifications succeeded in enhancing peptide-cell membrane affinity towards fluid anionic lipids and higher analgesic activity after systemic injection resulted therefrom. Here, we investigated if this affinity for anionic lipid membranes also translates into antimicrobial activity because bacteria have anionic membranes. Atomic force microscopy revealed that KTP derivatives perturbed Staphylococcus aureus membrane structure by inducing membrane blebbing, disruption and lysis. In addition, these peptides bind to red blood cells but are non-hemolytic. From the KTP derivatives tested, amidated KTP proves to be the most active antibacterial agent. The combination of analgesia and antibacterial activities with absence of toxicity is highly appealing from the clinical point of view and broadens the therapeutic potential and application of kyotorphin peptides.

In the treatment of patients with symptomatic irreversible pulpitis, endodontic debridement is a predictable method to relieve pain. However, there are clinical situations in which emergency care cannot be provided immediately. An unexplored treatment option in these cases may be the use of a long-acting anesthetic to reduce pain in untreated irreversible pulpitis. Some medical studies have shown potential for infiltrations of liposomal bupivacaine (Exparel; Pacira Pharmaceuticals, San Diego, CA) to prolong pain relief and reduce opioid use postoperatively. The Food and Drug Administration has approved Exparel only for infiltrations; therefore, the purpose of this study was to compare an infiltration of liposomal bupivacaine versus bupivacaine for pain control in untreated, symptomatic irreversible pulpitis. Ninety-five emergency patients received 2% lidocaine with 1:100,000 epinephrine via infiltration or an inferior alveolar nerve block to relieve their initial presenting pain. Patients then randomly received either 4 mL liposomal bupivacaine (13.3 mg/mL) or 4 mL 0.5% bupivacaine with 1:200,000 epinephrine by infiltration. Patients received a diary for the day of the appointment and 3 days postinjection to record soft tissue numbness, pain levels, and analgesic (non-narcotic and narcotic) use.

Cordia dichotoma G. Forst. is an important medicinal plant of family Boraginaceae. Traditionally, its leaves are used to treat fever, headache, and joint pain but its medicinal activities have not been proven by research. To evaluate the analgesic, anti-inflammatory, and antipyretic activity of C. dichotoma G. Forst. leaf extract. The various extracts of leaf powder were prepared by using soxhlet apparatus. The methanol extract was selected for pharmacological study. To evaluate analgesic activity, Eddy's hot plate method, to study anti-inflammatory activity, carageenan-induced rat paw edema method, and to study antipyretic activity, yeast-induced pyrexia method was used. SD female rats (180-200 g) were used for the study. In all three tests, the methanol extract high dose (400 mg/kg) was found to be highly significant as compared to standard drug. This study proved the traditional uses of plant leaves and concluded the analgesic, anti-inflammatory, and antipyretic activity of the leaf methanol extract.

Full Text Available This work has been done for the investigation of the anti-inflammatory and analgesic activity of methanol extract of dried leaves of Murraya koenigii Linn by oral administration at dose of 100, 200 and 400 mg/kg body weight, to healthy animals. Extract was studied for its anti-inflammatory activity by using carrageenan-induced hind paw edema in albino rats and the mean increase in paw volume and % inhibition in paw volume were measured plethysmometrically at different time intervals after carrageenan (1% w/v injection. Extract was also evaluated for analgesic activity using Eddy′s hot plate method and formalin induced paw licking method in albino rats. The methanol extract showed significant (P < 0.001 reduction in the carrageenan-induced paw edema and analgesic activity evidenced by increase in the reaction time by eddy′s hot plate method and percentage increase in pain in formalin test. The methanol extract showed anti-inflammatory and analgesic effect in dose dependent manner when compared with the control and standard drug, diclofenac sodium (10mg/kg, p.o. These inhibitions were statistically significant (P < 0.05. Thus our investigation suggests a potential benefit of Murraya koenigii in treating conditions associated with inflammatory pain.

Widespread use of and serious adverse effects associated with use of analgesics accentuates the need to consider factors related to analgesic use. The objective of this study was to describe continuous regular analgesics use and examine factors associated with a continuous regular analgesic use. The study was based on data from two surveys and included a random sample of women and men aged 18-45 years from the general Danish population. Information on analgesics use, self-rated health, demographic and lifestyle factors was collected using a self-administered questionnaire. A total of 28,000 women and 33 000 men were invited to participate and 22,199 women (response-rate 81.4%) and 23,080 men (response-rate 71.0%), respectively, were included in the study. Data were analyzed using multivariate logistic regression. We found that 27% of the women and 18% of the men reported a regular monthly use of at least seven analgesic tablets during the last year (continuous regular analgesics use). Besides poor self-rated health we found in both sexes that increasing age, poor self-rated fitness, and smoking were related to a continuous regular analgesics use. Nulliparity, low level of education, overweight/obesity, binge drinking, and abstinence were associated with a continuous regular analgesics use for women, while underweight and marital/cohabiting status were associated with a continuous regular analgesics use only for men. Regular monthly analgesic use during the last year was generally prevalent. Besides self-rated health, several socio-demographic and lifestyle factors were associated with a continuous regular analgesic use, although with some gender differences.

2013-03-01

Numerous lines of evidence suggest that heterocyclic compounds used as analgesic, anti-inflammatory and anti-migraine agents can be potent regulators of the nitroxidative stress and targeting free nitrogen and oxygen radicals is a very promising strategy for future pain management. Both classical analgesics (nonsteroidal anti-inflammatory drugs, opioid drugs) and many analgesic adjuvants, including desipramine, duloxetine, fluoxetine, paroxetine, escitalopram, phenytoin or carbamazepine and α-lipoic acid can modulate the balance between pro-oxidant and antioxidant processes in the mammalian tissues and these properties of drugs such as indomethacin, meloxicam, tenoxicam, valdecoxib or some metabolites of analgesic drugs formed by the activity of tissue peroxidases may contribute to their clinical efficacy and drug-related toxic effects, including gastrointestinal ulcers, hepatic failure, agranulocytosis, aplastic anemia, neutropenia, opiate-induced hyperalgesia and tolerance. The antioxidant capacities of novel heterocyclic compounds, including the compounds acting either by prevention of formation or catalyzed decomposition of peroxynitrite anion (ONOO-), namely the peroxynitrite decomposition catalysts or as superoxide (O2 •-)-scavengers which are the functional mimetics of superoxide dismutase (SOD) enzymes (SODm), as well as the derivatives of 6-nitro-3,4-methylenedioxyphenyl-Nacylhydrazone (LASSBio-881) or γ-butyrolactone (LPP1, BM113, BM113A, BM138 and BM138A) are also discussed as potent and promising future heterocyclic analgesics.

Full Text Available The present study aims to investigate the analgesic activity of the methanol extract of the galls of Quercus infectoria in rats using hot plate and tail-flick methods. The extract was administered intraperitoneally at a dose of 20 mg/kg while morphine sulfate and sodium salicylate (10 mg/kg served as standards. The methanol extract exhibited significant analgesic activity in the tail-flick model (P<0.05 by increasing the reaction time of the rats to 8.0 sec at 30 min after treatment in comparison to control (4.4 sec. Morphine sulfate produced a reaction time of 11.9 sec in the same test. At the peak of activity (30 min, the extract produced maximum possible analgesia (MPA of 34.2%, whilst morphine sulfate achieved a peak MPA of 70.9%. No analgesic effects have been observed using sodium salicylate in the tail-flick model. In the same model, the extract and sodium salicylate demonstrated comparable reaction times. Tail-flick is a better method to evaluate analgesic activity as no significant results were observed for all treatments using hot plate with the exception of morphine sulfate, which showed significant results only at 45 and 60 min after treatment. In conclusion, the methanol extract of the galls of Quercus infectoria displayed analgesic activity.

OBJECTIVE Given the increasing prevalence of obesity, more patients with a high body mass index (BMI) will require surgical treatment for degenerative spinal disease. In previous investigations of lumbar spine pathology, obesity has been associated with worsened postoperative outcomes and increased costs. However, few studies have examined the association between BMI and postoperative outcomes following anterior cervical discectomy and fusion (ACDF) procedures. Thus, the purpose of this study was to compare surgical outcomes, postoperative narcotics consumption, complications, and hospital costs among BMI stratifications for patients who have undergone primary 1- to 2-level ACDF procedures. METHODS The authors retrospectively reviewed a prospectively maintained surgical database of patients who had undergone primary 1- to 2-level ACDF for degenerative spinal pathology between 2008 and 2015. Patients were stratified by BMI as follows: normal weight (costs. Regression analyses were controlled for preoperative demographic and procedural characteristics. RESULTS Two hundred seventy-seven patients were included in the analysis, of whom 20.9% (n = 58) were normal weight, 37.5% (n = 104) were overweight, 24.9% (n = 69) were obese I, and 16.6% (n = 46) were obese II-III. A higher BMI was associated with an older age (p = 0.049) and increased comorbidity burden (p = 0.001). No differences in sex, smoking status, insurance type, diagnosis, presence of neuropathy, or preoperative VAS pain scores were found among the BMI cohorts (p > 0.05). No significant differences were found among these cohorts as regards operative time, intraoperative blood loss, length of hospital stay, and number of operative levels (p > 0.05). Additionally, no significant differences in postoperative narcotics consumption, VAS score improvement, complication rates, arthrodesis rates, reoperation rates, or total direct costs existed across BMI stratifications (p > 0.05).

The present study investigates the analgesic effect of minocycline, a semi-synthetic tetracycline antibiotic, in a rat model of inflammation-induced visceral pain. Inflammation was induced in male rats by intracolonic administration of tri-nitrobenzenesulphonic acid (TNBS). Visceral hyperalgesia was assessed by comparing the viscero-motor response (VMR) to graded colorectal distension (CRD) prior and post 7 days after TNBS treatment. Electrophysiology recordings from CRD-sensitive pelvic nerve afferents (PNA) and lumbo-sacral (LS) spinal neurons were performed in naïve and inflamed rats. Colonic inflammation produced visceral hyperalgesia characterized by increase in the VMRs to CRD accompanied with simultaneous activation of microglia in the spinal cord and satellite glial cells (SGCs) in the dorsal root ganglions (DRGs). Selectively inhibiting the glial activation following inflammation by araC (Arabinofuranosyl Cytidine) prevented the development of visceral hyperalgesia. Intrathecal minocycline significantly attenuated the VMR to CRD in inflamed rats, whereas systemic minocycline produced a delayed effect. In electrophysiology experiments, minocycline significantly attenuated the mechanotransduction of CRD-sensitive PNAs and the responses of CRD-sensitive LS spinal neurons in TNBS-treated rats. While the spinal effect of minocycline was observed within 5 min of administration, systemic injection of the drug produced a delayed effect (60 min) in inflamed rats. Interestingly, minocycline did not exhibit analgesic effect in naïve, non-inflamed rats. The results demonstrate that intrathecal injection of minocycline can effectively attenuate inflammation-induced visceral hyperalgesia. Minocycline might as well act on neuronal targets in the spinal cord of inflamed rats, in addition to the widely reported glial inhibitory action to produce analgesia. PMID:24485889

Methods: The whole plant of A. monsoniae was extracted with water and then subjected to preliminary chemical screening. It was then evaluated for in ova angiogenesis on fertilized white leg horn eggs using the concentrations of 200-600 毺 g/mL. The analgesic activity was evaluated in mice using the dose 100 and 250 mg/kg. The anti inflammatory activity was evaluated in rats using the dose 250 mg/kg and 500 mg/kg. In both the parameters water was used as the control and diclofenac was used the standard. The anti bacterial activity on Staphylococcus aureus and Pseudomonas aerugenosa was performed. Results: The phytochemical screening revealed the presence of tannins, flavonoids and saponins. The in ova angiogenesis revealed a dose dependent activity which proves the wound healing claim of the plant as more number of blood capillaries were formed at the site of the drug. The plant proved to be a potent analgesic and anti inflammatory agent at doses 1 00 mg/kg and 250 mg/kg. The anti bacterial activity was present but at higher doses. Conclusions: The parameters studied in the present investigation proved that the plant is a potent wound healer. Further in vivo wound healing studies on animal model is desired. As the extract showed potent analgesic, anti inflammatory and anti bacterial properties, it can be considered that when formulated into suitable formulation, and it can reduce the pain, inflammation and infections related to wound very well.

Living with pain is one of the distressing effects of food insecurity and malnutrition among millions of internally displaced persons (IDPs) worldwide. Vulnerability to emotional pain, metabolic imbalance, chronic illnesses and non-communicable diseases by IDPs are associated with stressed livelihood and restricted access to balanced diets in their camps. Tackling the complexity of issues related to internal displacement is challenging as 45% are globally trapped in protracted conditions. In this review, a diet-based intervention is proposed considering the potential benefits of nutrient synergy and analgesic constituents in organ meat. Providing an affordable, value added and well packaged nutrient dense diet is suggested to meet daily protein and micronutrient requirements from organ meat. Also, unlocking health-promoting bioactive substances and analgesics in restructured organ meat product is proposed as personalized dietary remedy to exert opioid bioactivity in food matrix. Exploiting the nutrient synergy of this animal by-product will not only improve the nutritional status or wellbeing but also raise the composite score of dietary diversity or food security index among IDPs by 2030.

Full Text Available Background: Pain is the major concern of patients attending dental clinics, and satisfactory pain relief has always been difficult to achieve. Since the pathophysiology of pain is a complex, central and peripheral nervous system process, combined analgesic regimens with different mechanisms of action as a multimodal approach are becoming popular among the clinicians and dentists. Objectives: The aim of the present study was to evaluate the analgesic and anti-inflammatory activity of ibuprofen and tramadol when used alone or in combination in animal models of pain and inflammation. Animals and Methods: The animals were divided into six groups with six animals in each group. Analgesic activity was assessed by hot plate method in rats and by acetic acid-induced writhing test in mice. Paw edema model in rats after induction with 0.1 mL of 1% carrageenan was used to assess the anti-inflammatory activity. Statistical Analysis: Analysis of variance followed by Tukey's honestly significant difference post hoc test was used for statistical analysis. Results and Conclusion: Combined use of tramadol and ibuprofen provided enhanced analgesic and anti-inflammatory effects in animal models of pain and inflammation.

Full Text Available Indian gooseberry (Emblica officinalis fruit, also known as “Amla” is one of the oldest edible fruits known in India. It has also traditionally been used to treat inflammation, and as an analgesic to treat wounds. However, experimental evidence for the analgesic effects of E. officinalis has been lacking. The present study investigated whether E. officinalis extracts exhibit analgesic effects in the plantar incision (PI and spared nerve injury (SNI pain-model rats. We evaluated the mechanical withdrawal threshold (MWT using von Frey filaments, and pain-related behavior was determined after surgery based on ultrasonic vocalization (USV. The group treated with E. officinalis extracts at 300 mg/kg had significantly increased MWT values at 6 h and 24 h after the PI, and had a significantly reduced number of 22–27-kHz USVs at 6 h and 24 h after PI. Moreover, after 15 days of continuous treatment with E. officinalis extracts, the treated group showed significantly alleviated SNI-induced hypersensitivity and reduced pro-inflammatory cytokine levels. Thus, E. officinalis extracts have potential analgesic effects in both postoperative and neuropathic pain models in vivo.

Full Text Available Abstract Background Pain and impaired mobility because of osteoarthritis (OA is common in dogs and humans. Efficacy studies of analgesic drug treatment of dogs with naturally occurring OA may be challenging, as a caregiver placebo effect is typically evident. However, little is known about effect sizes of common outcome-measures in canine clinical trials evaluating treatment of OA pain. Forty-nine client-owned dogs with hip OA were enrolled in a randomized, double-blinded placebo-controlled prospective trial. After a 1 week baseline period, dogs were randomly assigned to a treatment (ABT-116 – transient receptor potential vanilloid 1 (TRPV1 antagonist, Carprofen – non-steroidal anti-inflammatory drug (NSAID, Tramadol - synthetic opiate, or Placebo for 2 weeks. Outcome-measures included physical examination parameters, owner questionnaire, activity monitoring, gait analysis, and use of rescue medication. Results Acute hyperthermia developed after ABT-116 treatment (P P ≤ 0.01 and tramadol (P ≤ 0.001 led to improved mobility assessed by owner questionnaire. Nighttime activity was increased after ABT-116 treatment (P = 0.01. Kinetic gait analysis did not reveal significant treatment effects. Use of rescue treatment decreased with treatment in the ABT-116 and Carprofen groups (P R ≥ ±0.40, P ≤ 0.005. Placebo treatment effects were evident with all variables studied. Conclusion Treatment of hip OA in client-owned dogs is associated with a placebo effect for all variables that are commonly used for efficacy studies of analgesic drugs. This likely reflects caregiver bias or the phenomenon of regression to the mean. In the present study, outcome measures with significant effects also varied between groups, highlighting the value of using multiple outcome measures, as well as an a priori analysis of effect size associated with each measure. Effect size data from the present study could be used to inform design of future trials studying

Cordia verbenacea is a medicinal plant popularly used in Brazil as anti-inflammatory, antiulcer and anti-rheumatic agent without detailed pharmacological and toxicological studies. The study was aimed to investigate the effects of Cordia verbenacea in antiulcer, analgesic and antioxidant assays, as well as to evaluate its toxic effects and phytochemical profile. Antiulcer activity of plant extract was evaluated using ethanol/HCl, ethanol and piroxican-induced gastric lesions methods. The pH, volume and total acid of gastric juice were determined by pylorus-ligated assay. Analgesic activity was evaluated by writhing, tail-flick and hot-plate tests. Antioxidant activity was determined by in vitro lipoperoxidation assay. Acute toxicity and number of deaths were evaluated by Hippocratic screening. The ethanol leaf extract shows a potent antiulcer activity in the ethanol/HCl and absolute ethanol-induced gastric lesions. The IC(50) value of plant extract on the lipid peroxidation was 76.11mug/ml. Preliminary phytochemical tests were positive for flavonoids, steroids, saponins, fixed acids, alkaloids and phenols. In the analgesic models the extract did not present any activity. Cordial verbenaceae showed a potent antiulcer activity at the dose of 125mg/kg and this effect may be associated with an improvement in stomach antioxidant mechanisms.

Full Text Available Objective(sCurrent study was undertaken to investigate the analgesic and anti-inflammatory effects of the aqueous extract of Teucrium chamaedrys in mice and rats. Materials and MethodsFor evaluating of analgesic and anti-inflammatory activity, we used the carrageenan- and dextran-induced paw oedema, acetic acid-induced writhing, tail flick and formalin pain tests.ResultsThe extract of T. chamaedrys (50–200 mg/kg and acetylsalicylic acid (100 mg/kg produced a significant (P< 0.01 inhibition of the second phase response in the formalin pain model, while only the high dose (200 mg/kg of the extract showed an analgesic effect in the first phase. The extract also inhibited acetic acid-induced abdominal writhes in a dose-dependent manner. The tail flick latency was dose dependently enhanced by the extract but this was significantly (P< 0.05 lower than that produced by morphine (10 mg/kg. The extract (25–250 mg/kg administered 1 hr before carrageenan-induced paw swelling produced a dose dependent inhibition of the oedema. No effect was observed with the dextran-induced oedema model. Results of the phytochemical screening show the presence of alkaloids, flavonoids and triterpenoids in the extract.ConclusionThe data obtained also suggest that the anti-inflammatory and analgesic effects of the extract may be mediated via both peripheral and central mechanisms. The role of alkaloids, flavonoids and triterpenoids will evaluate in future studies.

GABA-ergic neurons are widely distributed throughout the central nervous system, including the spinal cord which is important for the transmission of pain impulses to the brain. Here we hypothesized that intrathecal baclofen (ITB) which is a GABA analogue might exert analgesic effects on neuropathic pain, which could be related to subtypes of pain in spinal cord injury (SCI). SCI patients with a cervical or thoracic lesion and neuropathic pain were randomized to receive either a single ITB bolus or placebo. Numerical Rating Scale (NRS), Neuropathic Pain Symptom Inventory (NPSI), and Brief Pain Inventory (BPI) were obtained for assessment of neuropathic pain. Spasticity was assessed using Modified Ashworth Scale and visual analogue scale. Evaluations were performed at baseline, and 4, 8, and 24 hours after application of ITB or placebo. Eight patients received ITB, 5 placebo. Neuropathic pain improved significantly in the ITB group based on NRS, BPI, and NPSI, which revealed an effect on all subtypes of pain. Spasticity declined significantly. In the placebo group, there was neither significant change in pain nor in spasticity. An ITB bolus exerted a significant analgesic effect on all subtypes of neuropathic pain in SCI patients. ITB has analgesic effects on all subtypes of neuropathic pain and can improve interference of neuropathic pain with activities of daily living. ITB might be a promising analgesic treatment to control neuropathic pain. Copyright © 2018. Published by Elsevier Inc.

Fisher, Michal; Bulatov, Vallery; Schechter, Israel

2003-01-01

A new technique is proposed for fast detection, identification and imaging of narcotic drugs in their solid phase. This technique, which requires only a tiny sample of a few microns, is based on microscopic chemical imaging. Minor sample preparation is required, and results are obtained within seconds. As far as we know, this is the most sensitive detection system available today for solid drugs. The technique can be applied for fast analysis of minute drug residues, and therefore is of considerable importance for forensic applications. It is shown that identification of drug traces in realistic matrixes is possible. Two main methods were applied in this study for detection of drugs and drug derivatives. The first method was based on direct detection and chemical imaging of the auto-fluorescence of the analyzed drugs. This method is applicable when the analyzed drug emits fluorescence under the experiment conditions, such as lysergic acid diethylamide (known as LSD). The second method was used for obtaining chemical imaging of drugs that do not fluoresce under the experiment conditions. In these cases fluorescent labeling dyes were applied to the examined samples (including the drug and the matrix). Both methods are simple and rapid, and require minor or no sample preparation at all. Detection limits are very low in the picogram range

Conotoxins Targeting Neuronal Voltage-Gated Sodium Channel Subtypes: Potential Analgesics?

Directory of Open Access Journals (Sweden)

Jeffrey R. McArthur

2012-11-01

Full Text Available Voltage-gated sodium channels (VGSC are the primary mediators of electrical signal amplification and propagation in excitable cells. VGSC subtypes are diverse, with different biophysical and pharmacological properties, and varied tissue distribution. Altered VGSC expression and/or increased VGSC activity in sensory neurons is characteristic of inflammatory and neuropathic pain states. Therefore, VGSC modulators could be used in prospective analgesic compounds. VGSCs have specific binding sites for four conotoxin families: μ-, μO-, δ- and ί-conotoxins. Various studies have identified that the binding site of these peptide toxins is restricted to well-defined areas or domains. To date, only the μ- and μO-family exhibit analgesic properties in animal pain models. This review will focus on conotoxins from the μ- and μO-families that act on neuronal VGSCs. Examples of how these conotoxins target various pharmacologically important neuronal ion channels, as well as potential problems with the development of drugs from conotoxins, will be discussed.

Approximately 18% of US adolescents engaged in prescription opioid abuse in 2013. However, this estimate may be misleading because it includes both medical misusers and nonmedical users, and there is evidence that these are 2 groups that differ relative to substance abuse and criminal risk. Thus, this study does not combine medical and nonmedical users; rather, it seeks to better understand the characteristics of nonmedical users. This was a school-based, cross-sectional study that was conducted during 2009-2010 in southeastern Michigan with a sample of 2627 adolescents using a Web-based survey. Three mutually exclusive groups were created based on responses regarding medical and nonmedical use of opioid analgesics. Group 1 had never used an opioid analgesic, Group 2 used an opioid analgesic only as prescribed, and Group 3 nonmedically used an opioid analgesic. In addition, Group 3 was divided into 2 mutually exclusive subgroups (self-treaters and sensation-seekers) based on reasons for nonmedical use. A series of multinomial logistic regressions were conducted to determine if the groups differed on the presence of pain, psychological symptoms (e.g., affective disorder, conduct disorder, attention-deficit/hyperactivity disorder [ADHD]), and drug abuse. Sixty-five percent (65.0%) of the sample was white/Caucasian and 29.5% was African American. The average age was 14.8 years (SD = 1.9). Seventy percent (70.4%; n = 1850) reported no lifetime opioid use, 24.5% (n = 644) were medical users, 3.5% (n = 92) were nonmedical users who used for pain relief only, and 1.6% (n = 41) were classified as nonmedical users for reasons other than for pain relief (e.g., to get high). Both medical users and nonmedical users reported more pain and substance abuse symptoms compared with never users. Those nonmedical users who used opioids for sensation-seeking motivations had greater odds of having psychological symptoms. These data support the need to further consider subgroups of

Full Text Available Inflammation is all a pervasive phenomenon, which is elicited by the body in response to obnoxious stimuli as a protective measure. However, sustained inflammation leads to several diseases including cancer. Therefore it is necessary to neutralize inflammation. Sonapatha (Oroxylum indicum, a medicinal plant, is traditionally used as a medicine in Ayurveda and other folk systems of medicine. It is commonly used to treat inflammatory diseases including rheumatoid arthritis and asthma. Despite this fact its anti-inflammatory and analgesic effects are not evaluated scientifically. Therefore, the anti-inflammatory and analgesic activities of Sonapatha (Oroxylum indicum were studied in Swiss albino mice by different methods. The hot plate, acetic acid, and tail immersion tests were used to evaluate the analgesic activity whereas xylene-induced ear edema and formalin induced paw edema tests were used to study the anti-inflammatory activity of Sonapatha. The administration of mice with 250 and 300 mg/kg b.wt. of O. indicum reduced pain and inflammation indicating that Sonapatha possesses analgesic and anti-inflammatory activities. The maximum analgesic and anti-inflammatory activities were observed in mice receiving 300 mg/kg b.wt. of O. indicum ethanol extract. Our study indicates that O. indicum possesses both anti-inflammatory and analgesic activities and it may be useful as an anti-inflammatory agent in the inflammation related disorders.

Full Text Available Background: Transversus abdominis plane (TAP block is suitable for lower abdominal surgeries. Blind TAP block has many complications and uncertainty of its effects. Use of ultrasonography increases the safety and efficacy. This study was conducted to evaluate the analgesic efficacy of ultrasound (USG-guided TAP block for retroperitoneoscopic donor nephrectomy (RDN. Methods: In a prospective randomized double-blind study, 60 patients undergoing laparoscopic donor nephrectomy were randomly divided into two groups by closed envelope method. At the end of surgery, USG-guided TAP block was given to the patients of both the groups. Study group (group S received inj. Bupivacaine (0.375%, whereas control group (group C received normal saline. Inj. Tramadol (1 mg/kg was given as rescue analgesic at visual analog scale (VAS more than 3 in any group at rest or on movement. The analgesic efficacy was judged by VAS both at rest and on movement, time to first dose of rescue analgesic, cumulative dose of tramadol, sedation score, and nausea score, which were also noted at 30 min, 2, 4, 6, 12, 18, and 24 h postoperatively. Total tramadol consumption at 24 h was also assessed. Results: Patients in group S had significantly lower VAS score, longer time to first dose of rescue analgesic (547.13±266.96 min vs. 49.17±24.95 min and lower tramadol consumption (103.8±32.18 mg vs. 235.8±47.5 mg in 24 h. Conclusion: The USG-guided TAP block is easy to perform and effective as a postoperative analgesic regimen in RDN, with opioids-sparing effect and without any complications.

Analgesic and anti-inflammatory activities of water (WE) and ethanolic (EE) extracts of Scoparia dulcis L. were investigated in rats and mice, and compared to the effects induced by Glutinol, a triterpene isolated by purification of EE. Oral administration (p.o.) of either WE or EE (up to 2 g/kg) did not alter the normal spontaneous activity of mice and rats. The sleeping time induced by sodium pentobarbital (50 mg/kg, i.p.) was prolonged by 2 fold in mice pretreated with 0.5 g/kg EE, p.o. Neither extract altered the tail flick response of mice in immersion test, but previous administration of EE (0.5 g/kg, p.o.) reduced writhings induced by 0.8% acetic acid (0.1 ml/10 g, i.p.) in mice by 47%. EE (0.5 and 1 g/kg, p.o.) inhibited the paw edema induced by carrageenan in rats by respectively 46% and 58% after 2 h, being ineffective on the paw edema induced by dextran. No significant analgesic or anti-edema effects were detected in animals pretreated with WE (1 g/kg, p.o.). Administration of Glutinol (30 mg/kg, p.o.) reduced writhing induced by acetic acid in mice by 40% and the carrageenan induced paw edema in rats by 73%. The results indicate that the analgesic activity of S. dulcis L. may be explained by an anti-inflammatory activity probably related to the triterpene Glutinol.

García-Larrea, L; Sindou, M; Mauguière, F

1989-11-01

Nociceptive flexion reflexes of the lower limbs (RIII responses) have been studied in 21 patients undergoing either epidural (DCS, n = 16) or transcutaneous (TENS, n = 5) analgesic neurostimulation (AN) for chronic intractable pain. Flexion reflex RIII was depressed or suppressed by AN in 11 patients (52.4%), while no modification was observed in 9 cases and a paradoxical increase during AN was evidenced in 1 case. In all but 2 patients, RIII changes were rapidly reversible after AN interruption. RIII depression was significantly associated with subjective pain relief, as assessed by conventional self-rating; moreover, in 2 patients it was possible to ameliorate the pain-suppressing effects of AN by selecting those stimulation parameters (intensity and frequency) that maximally depressed nociceptive reflex RIII. We recorded 2 cases of RIII attenuation after contralateral neurostimulation. AN appeared to affect nociceptive reflexes rather selectively, with no or very little effect on other cutaneous, non-nociceptive responses. Recording of RIII reflexes is relatively simple to implement as a routine paraclinical procedure. It facilitates the objective assessment of AN efficacy and may help to choose the most appropriate parameters of neurostimulation. In addition, RIII behavior in patients could be relevant to the understanding of some of the mechanisms involved in AN-induced pain relief.

Medicolegal autopsy reports from the Institute of Forensic Medicine University of Oslo concerning deaths from 2000 to 2009 were investigated. Those aged 20-59 whose manner of death was non-natural and who tested positive for any narcotic drug (morphine/heroin, amphetamines, ecstasy, cannabis, LSD, PCP, and high levels of GHB in addition to methadone and buprenorphine) were selected. All substance findings were registered and categorized (narcotics, ethanol, and medicinal products). Of the 1603 autopsies that met the selection criteria, 1204 were accidental intoxications, 122 accidents other than intoxication, 114 suicides by intoxication, 119 non-intoxication suicides, and 44 victims of homicide. Poly drug use was found in all manners of death. The drug profile as well as the mean number of substances (illicit drugs and medicinal products) varied from 2.9 to 4.6 substances per case, depending on the manner of death. Intoxication suicides had the highest number of substances and a total drug profile similar to accidental intoxications. Non-intoxication suicides had a total drug profile similar to homicide and accidents other than intoxication. The number of substances found per case increased during the decade, mainly due to increased findings of methadone, cannabis, amphetamines, and benzodiazepines. Methadone findings increased much more than buprenorphine. Methadone was found 20 times more often than buprenorphine in accidental intoxication cases. In summary, poly drug findings are common in adults who suffer a non-natural death while using illicit drugs. The different manners of death have some specific characteristics and significant differences regarding drug profile. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Opioid analgesic abuse is a complex and relatively new public health problem, and to date little is known about how the news media frame the issue. To better understand how this issue has been framed in public discourse, an analysis was conducted of the volume and content of news media coverage of opioid analgesic abuse over a 15-year period from 1998 to 2012 (N=673 news stories). A 70-item structured coding instrument was used to measure items in four domains that prior research suggests can influence public attitudes about health and social issues: causes, solutions, and consequences of the problem and individual depictions of persons who abuse opioid analgesics. Although experts have deemed opioid analgesic abuse a public health crisis, results of our study suggest that the news media more often frame the problem as a criminal justice issue. The most frequently mentioned cause of the problem was illegal drug dealing, and the most frequently mentioned solutions were law enforcement solutions designed to arrest and prosecute the individuals responsible for diverting opioid analgesics onto the illegal market. Prevention-oriented approaches, such as prescription drug-monitoring programs, were mentioned more frequently in the latter years of the study period, but less than 5% of news stories overall mentioned expanding substance abuse treatment, and even fewer mentioned expanding access to evidence-based medication-assisted treatments, such as buprenorphine. Findings underscore the need for a concerted effort to reframe opioid analgesic abuse as a treatable condition addressable via well-established public and behavioral health approaches.

Chalcone derivatives (3a-m) were prepared by condensing 4-aminoacetophenone with various substituted aromatic and hetero aromatic aldehydes according to Claisen-Schmidt condensation. These chalcones, on reaction with guanidine hydrochloride under basic alcoholic conditions gave 2,4,6-trisubstituted pyrimidines (5a-m) in quantitative yields. All the newly synthesized pyrimidines were characterized by means of IR, ¹H- and ¹³C-NMR, Electron Ionization (EI)-mass and elemental analyses and screened for anti-inflammatory and analgesic activities by in vivo. 2-amino-4-(4-aminophenyl)-6-(2,4-dichlorophenyl)pyrimidine (5b) and 2-amino-4-(4-aminophenyl)-6-(3-bromophenyl) pyrimidine (5d) were found to be the most potent anti-inflammatory and analgesic activity compared with ibuprofen, reference standard. And also it was found that compound 5b identified as lead structure among all in both the activities. Pyrimidines which showed good anti-inflammatory activity also displayed better analgesic activity.

Secondary metabolites from plants are a good source for the NSAID drug development. We studied the analgesic activity of ethanolic extract of Erythrina variegata L. (Fabaceae) followed by molecular docking analysis. The analgesic activity of Erythrina variegata L. is evaluated by various methods viz., acetic acid-induced writhing test, hot plate and tail immersion test. Subsequently, molecular docking analysis has been performed to identify compounds having activity against COX-1 and COX-2 enzymes by using GOLD docking fitness. The result of preliminary phytochemical screening revealed that the extract contains alkaloids and flavonoids. In analgesic activity tests, the extract at the doses of 50, 100 and 200 mg/kg body weight (b.w.) produced a increase in pain threshold in a dose dependent manner. In acetic acid induced writhing test, the inhibitory effect was similar to the reference drug diclofenac sodium. The extract showed 18.89% writhing inhibitory effect at the dose 200 mg/kg b.w., whereas diclofenac sodium showed 79.42% inhibition of writhing at a dose of 10 mg/kg b.w. The results of tail immersion and hot plate test also showed potential analgesic activity of the extract which is also comparable to the standard drug morphine (5 mg/kg b.w.). Docking studies shows that phaseollin of Erythrina variegata L. has the best fitness score against the COX-1 which is 56.64 and 59.63 for COX- 2 enzyme. Phaseollin of Erythrina variegata L. detected with significant fitness score and hydrogen bonding against COX-1 and COX-2 is reported for further validation.

The current retrospective study was completed with the aim to identify demographic characteristics and clinical predictors (if any) of the patients discharged from our pain clinic due to breach in narcotic use contract (BNUC). Retrospective patient charts' review and data audit. University hospital-affiliated pain clinic in the United States. All patient charts in our pain clinic for a 2-year period (2011-2012). The patients with BNUC were delineated from the patients who had not been discharged from our pain clinic. Pain characteristics, pain management, and substance abuse status were compared in each patient with BNUC between the time of admission and the time of discharge. The patients with BNUC discharges showed significant variability for the discharging factors among the pain physicians within a single pain clinic model with this variability being dependent on their years of experience and their proactive interventional pain management. The patients with BNUC in our pain clinic setting were primarily middle-aged, obese, unmarried males with nondocumented stable occupational history who were receiving only noninterventional pain management. Substance abuse, doctor shopping, and potential diversion were the top three documented reasons for BNUC discharges. In 2011-2012, our pain clinic discharged 1-in-16 patients due to breach in narcotic use contract.

Psidium cattleianum Sabine is extensively used in Brazilian traditional medicine to treat several diseases including painful disorders. Aim of the study to investigate the toxicity and the possible analgesic activities of the hydroalcoholic extract from the leaves of Psidium cattleianum Sabine (ELPCS), to support its use in folk medicine. To screen the major phytochemical constituents of this extract and evaluate their antioxidant activity. ELPCS was assessed for its antioxidant activity using the DPPH model. Its analgesic activity was examined using mouse models of acetic acid-induced writhing and hot plate paw licking models. The major phytochemical constituents of the extract were screened; their toxicity on LLC-MK2 mammalian cells was evaluated. ELPCS exhibited significant peripheral analgesic activity at doses of 60, 80, 100, 200 and 400mg/kg in mice, but it did not display central analgesic activity and not was toxic to LLC-MK2 cell (LD50>400 µg/mL). The extract exhibited free radical scavenging activity as evidenced by IC50 values (15.9 µg/mL) obtained by the DPPH method. Phytochemical screening detected flavonoids, saponins, cardiac glycosides, anthraquinones, and tannins. The results of the experimental studies proved the analgesic activity of ELPCS and supported the traditional use of this plant. © 2013 Elsevier Ireland Ltd. All rights reserved.

The object of this study is to investigate the prevalence and characteristics of headache in Korean professional women breath-hold divers, including their overuse of analgesics. Headache is a common problem encountered in clinical practice, and undersea divers exhibit unique causes of headache in addition to other common primary headaches. Many scuba divers are known to use various types of drugs to overcome dive-related symptoms or to enhance their underwater performance. The target population of this study was women divers in the northern district of Jeju Island who were registered in the divers' union. Data were collected using telephone interviews with a structured questionnaire. Headache was diagnosed and classified according to criteria of the International Headache Society. Nine hundred and eleven (80.3%) divers responded to the telephone interview. The prevalence rates of headache were 21.4% for tension-type headache and 9.1% for migraine. One hundred and four divers (11.4%) fulfilled the criteria for chronic daily headache (CDH). Overuse of combination analgesics was reported by 70.7% of divers. Women divers with CDH were significantly older and they complained more of tinnitus and dizziness, and had a greater history of hypertension than divers without headache. The prevalence of CDH is high in Korean professional women breath-hold divers, with many of them being combination-analgesics overusers.

Gentiopicroside is one of the secoiridoid compound isolated from Gentiana lutea. It exhibits analgesic activities in the mice. The anterior cingulate cortex (ACC) is a forebrain structure known for its roles in pain transmission and modulation. Painful stimuli potentiate the prefrontal synaptic transmission and induce glutamate NMDA NR2B receptor expression in the ACC. But little is known about Gentiopicroside on the persistent inflammatory pain and chronic pain-induced synaptic transmission changes in the ACC. The present study was undertaken to investigate its analgesic activities and central synaptic modulation to the peripheral painful inflammation. Gentiopicroside produced significant analgesic effects against persistent inflammatory pain stimuli in mice. Systemic administration of Gentiopicroside significantly reversed NR2B over-expression during the chronic phases of persistent inflammation caused by hind-paw administration of complete Freunds adjuvant (CFA) in mice. Whole-cell patch clamp recordings revealed that Gentiopicroside significantly reduced NR2B receptors mediated postsynaptic currents in the ACC. Our findings provide strong evidence that analgesic effects of Gentiopicroside involve down-regulation of NR2B receptors in the ACC to persistent inflammatory pain.

Several additives have been suggested to enhance analgesic effect of local anesthetic agents to decrease the adverse effects of them and increase the degree of satisfaction. We designed this randomized double-blind controlled study to evaluate the analgesic efficacy of the neostigmine added to bupivacaine using spinal anesthesia in patients undergoing lower limb orthopedic surgery. Sixty patients 18-80 yr old American Society of Anesthesiologists (ASA) physical status I or II, scheduled for femur surgery under spinal anesthesia, were recruited in a prospective, double-blinded, randomized way. The patients were randomly allocated to one of two groups of 30 each. The neostigmine group (group N) received bupivacaine 20 mg combined with 25 µg neostigmine, and the placebo group (group C) received bupivacaine 20 mg combined with 0.5ml distilled water (intrathecally) 5 minutes prior to surgery. The time to the first analgesic request, analgesic requirement in the first 12 hours after surgery, the duration of sensory and motor blockade, the incidence of adverse effects such as nausea,vomiting,hypotension, ephedrine requirements, bradycardia, and hypoxemia were recorded. Patients receiving neostigmine had a significantly prolonged duration of motor block (C95% CI 30.27 to 87.65; P < 0.001) and sensory block (C95% CI 101.04 to 224.64; P < 0.001) compared to the control group. The difference of the mean time to the first analgesic request was also significantly longer in neostigmine group (C95% CI 83.139 to 208.526; P < 0.001). The total analgesic consumption during the first 12 hours after surgery was devoid of any significant difference between groups N and C (p = 0.41).The two groups were not significantly different in terms of intraoperative and postoperative side effects. Intrathecal neostigmine 25 µg with bupivacaine caused a prolonged time to the first analgesic request and its use was not associated with any side effects.

Heptapeptide Semax (MEHFPGP) is the fragment of ACTH(4-10) analogue with prolonged neurotropic activity. The aim of the present work was to study the Semax effects on learning capability and pain sensitivity in white rats following intraperitoneal and intranasal administration in different doses. Semax nootropic effects were studied in the test of acquisition of passive avoidance task. Pain sensitivity was estimated in Randall-Selitto paw-withdrawal test. It was shown that Semax exerts nootropic and analgesic activities following intraperitoneal administration. Analysis of dependence of these effects on dose resulted in different dose-response curves. Following intranasal administration, Semax was more potent in learning improvement compared to intraperitoneal administration. The peptide failed to affect the animal pain sensitivity following intranasal administration as opposed to intraperitoneal administration. The data obtained suggest different mechanisms and brain structures involved in realization of the nootropic and analgesic effects of Semax.

2004-01-01

The influence of circulating serotonin (5-HT) on the effects of intra-articular administration of granisetron on temporomandibular joint (TMJ) pain was investigated in 11 patients with chronic polyarthritides. An analgesic effect superior to placebo has been shown previously. The change in TMJ movement pain intensity was negatively correlated to circulating 5-HT; that is, the higher the 5-HT before injection, the greater the reduction of pain intensity. The resting pain intensity reduction was not related to 5-HT. In conclusion, this study indicates a stronger short-term analgesic effect on TMJ movement pain by intra-articular administration of the 5-HT3 receptor antagonist granisetron in patients with high levels of circulating 5-HT.

Full Text Available Ibuprofen is classified as a BCS class II drug which has low solubility and high permeability. We conducted the formation of the cocrystalline phase of ibuprofen with coformer nicotinamide to increase its solubility. The purpose of this study was to characterize the solid state of cocrystalline phase of ibuprofen-nicotinamide, determine the solubility, and evaluate its in vivo analgesic activity. The cocrystal of ibuprofen-nicotinamide was prepared by a slow evaporation method. The solid-state characterization was conducted by powder X-ray diffraction (PXRD analysis, differential thermal analysis (DTA, and scanning electron microscopy (SEM. To investigate the in vivo analgesic activity, 28 male Swiss-Webster mice were injected with acetic acid 0.5% following oral administration of intact ibuprofen, physical mixture, and its cocrystalline phase with nicotinamide (equivalent to 26 mg/kg ibuprofen. The number of writhes was counted, and pain inhibition was calculated. All data were analyzed with one-way ANOVA followed by Duncan’s Multiple Range Test (95% confidence interval. The results revealed that a new cocrystalline phase was successfully formed. The solubility testing showed that the cocrystal formation enhanced the solubility significantly as compared with the physical mixture and intact ibuprofen. A significant increase in the analgesic activity of cocrystal ibuprofen-nicotinamide was also confirmed.

A better understanding of the analgesia needs of patients who undergo common operative procedures is necessary as we address the growing opioid public health crisis in the United States. The aim of this study was to evaluate patient experience with our opioid prescribing practice after elective inguinal hernia repairs. A prospective, observational study was conducted between October 1, 2015, and September 30, 2016, in a single-surgeon, high-volume, practice of inguinal hernia operation. Adult patients undergoing elective inguinal herniorrhaphy under local anesthesia with intravenous sedation were invited to participate. All patients were prescribed 10 opioid analgesic tablets postoperatively and were counseled to reserve opioids for pain not controlled by nonopioid analgesics. Their experience was captured by completing a questionnaire 2 to 3 weeks postoperatively during their postoperative visit. A total of 185 patients were surveyed. The majority of the participants were males (177, 95.7%) and ≥60 years old (96, 51.9%). Of the 185 patients, 159 (85.9%) reported using ≤4 opioid tablets; 110 patients (59.5%) reported that they used no opioid analgesics postoperatively. None of the patients was taking opioids within 7 days of their postoperative appointment. Of the 147 patients who were employed, 111 (75.5%) reported missing ≤3 work days, 57 of whom (51.4%) missed no work at all. Patients who were employed were more likely to take opioid analgesics postoperatively (P = .049). Patients who took no opioid analgesics experienced less maximum (P require any opioid analgesics, and nearly all of those who thought that they did need opioids used reserved.

The purpose of this trial was to investigate whether breast milk (either breastfed or bottle-fed) has a better analgesic effect than sucrose in newborns born at a postmenstrual age between 32 and 37 weeks. We conducted a randomized controlled trial at a secondary care neonatal unit in the Netherlands on 71 preterm neonates (postmenstrual age at birth 32-37 weeks), undergoing heel lance with an automated piercing device. Newborns were randomly assigned to breast milk (either breastfed or bottle-fed) administered during heel lance or oral sucrose administered before heel lance. We assessed the Premature Infant Pain Profile (PIPP) score (range, 0-21) to investigate whether there was a difference in pain score between neonates receiving breast milk and those receiving sucrose solution. There was no significant difference in mean PIPP score between neonates receiving breast milk (6.1) and those receiving sucrose (5.5), with a mean difference of 0.6 (95% confidence interval -1.6 to 2.8; P = .58). From this study, it cannot be concluded that breast milk has a better analgesic effect than sucrose in late preterm infants. From the results, it follows with 95% confidence that the analgesic effect of breast milk is not >1.6 points better and not > 2.8 points worse on the PIPP scale (SD 3.7) than the analgesic effect of sucrose in late preterm infants.
